An aqueous molecular tube composed of polyaromatic frameworks with peripheral hydrophilic groups was prepared. The new tube has a well-defined hydrophobic cavity with a diameter of ∼1 nm and quantitatively binds two molecules of fluorescent coumarin dyes in aqueous solutions. The bound coumarin dimers in a stacked fashion exhibit unusual excimer-like emissions in the confined space through efficient host-guest energy transfer. ...[more]

Project description:A series of 2- and 3-OH Nile red dyes was prepared in order to generate water-soluble probes that could be used to probe lipid binding to proteins. Various substitutions in positions 2-/3-, 6-, and 7-shifted wavelengths while maintaining the environmental sensitivity of Nile red. In order to increase the solubility of the dyes in aqueous solutions, we attached butyric acid groups to the 2- or 3-OH position. In addition, phenothiazine dyes, which exhibited particularly long excitation properties, were synthesized and tested for the first time. All dyes showed Stoke's shifts of 70-100 nm and changes in excitation and emission of over 100 nm, depending on the hydrophobicity of the environment. Binding studies with bovine serum albumin and the non-specific lipid transfer protein SCP2 revealed emission changes of more than 30 nm upon binding to the protein and a five-fold increase in emission intensity. Titration of the dye-loaded proteins with various lipids or drugs replaced the dye and thereby reversed the shift in wavelength intensity. This allowed us to estimate the lipid binding affinity of the investigated proteins. For SCP2, isothermal calorimetry (ITC) data verified the titration experiments. NMR titration experiments of SCP2 with Nile red 2-O-butyric acid (1a) revealed that the dye is bound within the lipid binding pocket and competes with lipid ligands for this binding site. These results give valuable insight into lipid and drug transport by proteins outside and inside cells.

Project description:The simultaneous measurement of gene expression for thousands of genes in a single analysis by the microarray technology allows researchers to describe transcriptomes in various samples of interest. Problems with variation in data quality derived from microarray experiments are well known and might result from poor RNA quality, background problems, or sub optimal signal strength. To assess variation due to the fluorescent dye chosen, three different dye pairs were tested for labelling of cDNA in gene expression analysis experiments on a porcine immune focused oligonucleotide microarray (POM3). This in-house oligonucleotide microarray allowed a direct comparison of background fluorescence, Median signal intensities, numbers of spots detected, and resistance to photobleaching between different dye pairs. We tested Alexa Flour 546/647, Cy3/Cy5 as well as Oyster 550/650 all from Genisphere Inc., Hatfield, PA, USA. Keywords: Comparison of fluorescent dyes

Project description:PurposeThe aim was to evaluate fluorescent molecular rotors (DCVJ and CCVJ), which are mainly sensitive to viscosity, for the characterization of polysorbate-containing IgG formulations and compare them to the polarity-sensitive dyes ANS, Bis-ANS and Nile Red.MethodsIgG formulations with polysorbate 20 or 80 were stressed below the aggregation temperature and analyzed by steady-state and time-resolved fluorescence and by HP-SEC with UV and fluorescent dye detection (Bis-ANS and CCVJ). Furthermore, commercial protein preparations of therapeutic proteins (Enbrel 50 mg, Humira 40 mg and MabThera 100 mg) were aggregated accordingly and analyzed with CCVJ fluorescence and HP-SEC.ResultsContrarily to (Bis-)ANS and Nile Red, the molecular rotors DCVJ and CCVJ showed low background fluorescence in polysorbate-containing buffers. Time-resolved fluorescence experiments confirmed the steady-state fluorescence data. Both DCVJ and CCVJ showed enhanced fluorescence intensity for aggregated IgG formulations and were suitable for the characterization of polysorbate-containing IgG formulations in steady-state fluorescence and HP-SEC with dye detection (CCVJ). CCVJ was capable of detecting thermally induced aggregation in the commercial polysorbate-containing products Enbrel 50 mg, Humira 40 mg and MabThera 100 mg.ConclusionFluorescent molecular rotors are suitable probes to detect aggregation in polysorbate-containing IgG formulations.

We tested Alexa Flour 546/647, Cy3/Cy5 as well as Oyster 550/650 all from Genisphere Inc., Hatfield, PA, USA. Keywords: Comparison of fluorescent dyes Each dye pairs were hybridized on two slides. The same two samples were compared on all the slides used in the present study. The liver sample from a healthy animal was labeled with the high wavelength dyes (Oyster 650/Alexa 647/Cy5) and the liver sample from the sick animal was labeled with the low wavelength dyes (Oyster 550/Alexa 546/Cy3). Each slide was scanned 3 times, immediately after hybridization (first round), after 1 month of storage in darkness and after 24 hours on the bench (12 hours of daylight and 12 hours of artificial light). Total RNA from the infected and control liver samples were extracted using RNeasy midi kit (Qiagen, Denmark) and DNase treated using RNase-Free DNase Set (Qiagen). 3DNATM Array 900 expression array detection kits (Genisphere Inc.) were used for the labeling and cDNA synthesis reaction of the RNA in the present study. Three different pairs of fluorescent dyes Oyster 550/650 (Genisphere Inc.), Alexa 546/647 (Genisphere Inc.), and Cy3/Cy5 (Genisphere Inc.) were used in separate labeling reactions. Labeling was done according to the manufacturers protocol for large-scale cDNA synthesis. For the cDNA synthesis 9.2µg total RNA from each liver sample was used and mixed with 20U AmpliQ RTenzyme and 10x first strand buffer (Bie og Berntsen, Rødovre, Denmark). Hybridization and washing were performed according to the manufacturers instructions (Genisphere) using Corning hybridization chambers. For one cDNA hybridization reaction; 6.5µl cDNA from each synthesis, 0.5µl Salmon sperm (10µg/µl) and 13.5µl 2 x Formamide-Based Hybridization Buffer (3DNA Array 900, Genisphere) was used. A total hybridization mix of 29µl was applied under a 22I x 25 mm LifterSlip (Erie Scientific, Portsmouth, NH, USA) carefully avoiding air bubbles. Slides were incubated at 44oC in a water bath over night. Wash buffer 1 (3DNA Array 900, Genisphere) was preheated to 44oC for the post cDNA hybridization wash. For two 3DNA hybridization reaction mixes; 2.5µl of each Capture reagent and 26µl SDS-Based hybridization buffer was mixed to a final volume of 52µl. 26µl 3DNA hybridization mix was applied to each slide, and incubated in darkness in a water bath at 50oC for 4 hours. Wash buffer 1 was preheated to 60oC for the post 3DNA hybridization wash. Slides were scanned on a CCD ArrayWoRxe auto (Applied Precision, Issaquah, WA, USA) using different exposure times (0.3 for 595 nm and 1.2 for 685 nm).

Project description:The Qubit fluorometer is a DNA quantification device based on the fluorescence intensity of fluorescent dye binding to double-stranded DNA (dsDNA). Qubit is generally considered useful for checking DNA quality before next-generation sequencing because it measures intact dsDNA. To examine the most accurate and suitable methods for quantifying DNA for quality assessment, we compared three quantification methods: NanoDrop, which measures UV absorbance; Qubit; and quantitative PCR (qPCR), which measures the abundance of a target gene. For the comparison, we used three types of DNA: 1) DNA extracted from fresh frozen liver tissues (Frozen-DNA); 2) DNA extracted from formalin-fixed, paraffin-embedded liver tissues comparable to those used for Frozen-DNA (FFPE-DNA); and 3) DNA extracted from the remaining fractions after RNA extraction with Trizol reagent (Trizol-DNA). These DNAs were serially diluted with distilled water and measured using three quantification methods. For Frozen-DNA, the Qubit values were not proportional to the dilution ratio, in contrast with the NanoDrop and qPCR values. This non-proportional decrease in Qubit values was dependent on a lower salt concentration, and over 1 mM NaCl in the DNA solution was required for the Qubit measurement. For FFPE-DNA, the Qubit values were proportional to the dilution ratio and were lower than the NanoDrop values. However, electrophoresis revealed that qPCR reflected the degree of DNA fragmentation more accurately than Qubit. Thus, qPCR is superior to Qubit for checking the quality of FFPE-DNA. For Trizol-DNA, the Qubit values were proportional to the dilution ratio and were consistently lower than the NanoDrop values, similar to FFPE-DNA. However, the qPCR values were higher than the NanoDrop values. Electrophoresis with SYBR Green I and single-stranded DNA (ssDNA) quantification demonstrated that Trizol-DNA consisted mostly of non-fragmented ssDNA. Therefore, Qubit is not always the most accurate method for quantifying DNA available for PCR.

Project description:Herein, we present a new synthetic route to cyanine-based heterobifunctional dyes and their application as fluorescent linkers between polymers and biomolecules. The synthesized compounds, designed in the visible spectral range, are equipped with two different reactive groups for highly selective conjugation under physiological conditions. By applying indolenine precursors with functionalized benzenes, we achieved water-soluble asymmetric cyanine dyes bearing maleimido and N-hydroxysuccinimidyl functionalities in a three-step synthesis. Spectroscopic characterization revealed good molar absorption coefficients and moderate fluorescence quantum yields. Further reaction with polyethylene glycol yielded dye-polymer conjugates that were subsequently coupled to the antibody cetuximab, often applied in cancer therapy. Successful coupling was confirmed by mass shifts detected by gel electrophoresis. Receptor-binding studies and live-cell imaging revealed that labeling did not alter the biological function. In sum, we provided a successful synthetic pathway to rigid heterobifunctional cyanine dyes that are applicable as fluorescent linkers, for example, for connecting antibodies with macromolecules. Our approach contributes to the field of bioconjugation chemistry, such as antibody-drug conjugates by combining diagnostic and therapeutic approaches.

Project description:We describe the design, synthesis and fluorescent profile of a family of environment-sensitive dyes in which a dimethylamino (donor) group is conjugated to a cyanoacrylate (acceptor) unit via a cyclopenta[b]naphthalene ring system. This assembly satisfies the typical D-?-A motif of a fluorescent molecular rotor and exhibits solvatochromic and viscosity-sensitive fluorescence emission. The central naphthalene ring system of these dyes was synthesized via a novel intramolecular dehydrogenative dehydro-Diels-Alder (IDDDA) reaction that permits incorporation of the donor and acceptor groups in variable positions around the aromatic core. A bathochromic shift of excitation and emission peaks was observed with increasing solvent polarity but the dyes exhibited a complex emission pattern with a second red emission band when dissolved in nonpolar solvents. Consistent with other known molecular rotors, the emission intensity increased with increasing viscosity. Interestingly, closer spatial proximity between the donor and the acceptor groups led to decreased viscosity sensitivity combined with an increased quantum yield. This observation indicates that structural hindrance of intramolecular rotation dominates when the donor and acceptor groups are in close proximity. The examined compounds give insight into how excited state intramolecular rotation can be influenced by both the solvent and the chemical structure.

Project description:Exoglycosidases are often used for detailed characterization of glycan structures. Bovine kidney ?-fucosidase is commonly used to determine the presence of core ?1-6 fucose on N-glycans, an important modification of glycoproteins. Recently, several studies have reported that removal of core ?1-6-linked fucose from N-glycans labeled with the reactive N-hydroxysuccinimide carbamate fluorescent labels 6-aminoquinolyl-N-hydroxysuccinimidylcarbamate (AQC) and RapiFluor-MS is severely impeded. We report here the cloning, expression and biochemical characterization of an ?-fucosidase from Omnitrophica bacterium (termed fucosidase O). We show that fucosidase O can efficiently remove ?1-6- and ?1-3-linked core fucose from N-glycans. Additionally, we demonstrate that fucosidase O is able to efficiently hydrolyze core ?1-6-linked fucose from N-glycans labeled with any of the existing NHS-carbamate activated fluorescent dyes.

Project description:Three-dimensional fluorescent graphene frameworks with controlled porous morphologies are of significant importance for practical applications reliant on controlled structural and electronic properties, such as organic electronics and photochemistry. Here we report a synthetically accessible approach concerning directed aromatic stacking interactions to give rise to new fluorogenic 3D frameworks with tuneable porosities achieved through molecular variations. The binding interactions between the graphene-like domains present in the in situ-formed reduced graphene oxide (rGO) with functional porphyrin molecules lead to new hybrids via an unprecedented solvothermal reaction. Functional free-base porphyrins featuring perfluorinated aryl groups or hexyl chains at their meso- and β-positions were employed in turn to act as directing entities for the assembly of new graphene-based and foam-like frameworks and of their corresponding coronene-based hybrids. Investigations in the dispersed phase and in thin-film by XPS, SEM and FLIM shed light onto the nature of the aromatic stacking within functional rGO frameworks (denoted rGOFs) which was then modelled semi-empirically and by DFT calculations. The pore sizes of the new emerging reduced graphene oxide hybrids are tuneable at the molecular level and mediated by the bonding forces with the functional porphyrins acting as the "molecular glue". Single crystal X-ray crystallography described the stacking of a perfluorinated porphyrin with coronene, which can be employed as a molecular model for understanding the local aromatic stacking order and charge transfer interactions within these rGOFs for the first time. This opens up a new route to controllable 3D framework morphologies and pore size from the Ångstrom to the micrometre scale. Theoretical modelling showed that the porosity of these materials is mainly due to the controlled inter-planar distance between the rGO, coronene or graphene sheets. The host-guest chemistry involves the porphyrins acting as guests held through π-π stacking, as demonstrated by XPS. The objective of this study is also to shed light into the fundamental localised electronic and energy transfer properties in these new molecularly engineered porous and fluorogenic architectures, aiming in turn to understand how functional porphyrins may exert stacking control over the notoriously disordered local structure present in porous reduced graphene oxide fragments. By tuning the porosity and the distance between the graphene sheets using aromatic stacking with porphyrins, it is also possible to tune the electronic structure of the final nanohybrid material, as indicated by FLIM experiments on thin films. Such nanohybrids with highly controlled pores dimensions and morphologies open the way to new design and assembly of storage devices and applications incorporating π-conjugated molecules and materials and their π-stacks may be relevant towards selective separation membranes, water purification and biosensing applications.

Project description:Screening of bead-based peptide libraries against fluorescent dye-labeled target proteins was found to be significantly influenced by the dye characteristics. Commercially available red fluorescent dyes with net negative charges adversely showed strong interactions with library beads. The introduction of zwitterionic dyes significantly reduced the unwanted interactions, which sheds light upon using the right fluorescent probe for acquisition of reliable results in various fluorescence-assisted applications.
