Case study for MOSS algorithm: LC-MS raw data of bourbon

ABSTRACT: A Thermo Vanquish UPLC system (ThermoFisher, Waltham, MA, USA) coupled with a Hybrid Quadrupole Orbitrap Q Exactive mass spectrometer (ThermoFisher) was used for small molecule analysis of study samples. Bourbon molecules were separated using an Xbridge BEH Amide (2.5 um, 2.1 x 150 mm, Waters, Milford, MA, USA) column. The mobile phases consisted of solvents A and B, where A contained 5 mM ammonium acetate, 0.1% acetic acid in 90% H2O/10% acetonitrile (ACN) and B contained 5 mM ammonium acetate, 0.1% acetic acid in 10% H2O/90% ACN. A gradient of mobile phase injection was used for 20 minutes at a flow rate of 0.3 mL/min, starting with 30% of mobile phase A and increasing to 70% at 5 min. The proportion of mobile phase A was maintained at 70% until 9 min, and then started to decrease to 30% until 11 min. The percentage of solvent A was then kept at 70% until 20 min, after which it gradually returned to 30% to prepare for the next injection. To observe and prove the consistency of the instrument during testing and to enable data normalization, a pooled quality control (QC) was added to the sample tray after every ten sample injections in both sequences. A blank sample was added after each QC sample.

Project description:MicroPoly(A)Pure kits (Ambion) were used to prepare mRNA from P. salmonis-infected and control Atlantic salmon head kidney. Head kidney mRNA samples were prepared from pooled (n = 10) infected or control kidney. Approximately 200 ng of infected or control head kidney mRNA was used as template in aRNA synthesis reactions. Two infected head kidney samples were pooled to yield 8.9 ug of aRNA, and a single control head kidney sample contained 8.4 ug of aRNA. Infected and control head kidney aRNA samples were visualized on agarose gels to check quality and quantity (data not shown). Except for the amounts of aRNA and reverse transcription (RT) primer used, head kidney target labeling reactions and microarray hybridizations were identical. Head kidney target syntheses used 2 ug of aRNA and 2 ug of random primers (Roche). RT primers were mixed with aRNA samples, and nuclease-free H2O (Invitrogen) was added to make 10 ul total volume. Samples were incubated at 70 degrees C for 4 min, then placed on ice. RT reactions included 50 mM Tris HCl pH 8.3, 75 mM KCl, 3 mM MgCl2, 10 mM DTT, 0.5 mM each dATP, dCTP, and dGTP, 0.2 mM dTTP, 0.05 mM Cy3-dUTP or Cy5-dUTP (Amersham), 40U RNAguard ribonuclease inhibitor (Amersham), and 400U Superscript II Rnase H- reverse transcriptase (Invitrogen). RT reactions were incubated at 42 degrees C for 2.5 h, followed by addition of 0.025U RNase A (Sigma) and 1.5U RNase H (New England BioLabs) and incubation at 37 degrees C for 30 min. Labeled targets were cleaned using the Qiaquick PCR purification kit (Qiagen) and precipitated, with 300 mM sodium acetate, 1 ul of 20 ug/ul glycogen (Invitrogen), and 2.5 volumes of 100% ethanol, at -20 degrees C overnight. Each labeled target was recovered by centrifugation (14,000 rpm, 4 degrees C, 1 h), washed in 70% ethanol, air-dried, and resuspended in 60 ul of hybridization buffer: 50% deionized formamide, 5X SSC, 0.1% SDS, 5 ul of 5 ug/ul oligo dT (5’T18[Q-N]3’), 5 ul of 2 ug/ul BSA (Pierce), and 2 ul of 10 ug/ul sonicated human placental DNA (Sigma). Targets were incubated at 96 degrees C for 3 min, and then at 65 degrees C until applied to microarrays. Microarrays were prepared for hybridization by washing 2 X 5 min in 0.1% SDS, washing 5 X 1 min in MilliQ H2O, immersing 3 min in 95 degrees C MilliQ H2O, and drying by centrifugation (2000 rpm, 5 min, in 50 ml conical tube). Microarray hybridizations were run in the dark under HybriSlips hybridization covers (Grace Biolabs) in slide hybridization chambers (Corning) submerged in a 45 degrees C water bath for 16 h. Coverslips were floated off in 45 degrees C (1X SSC, 0.2% SDS), and arrays were washed 1 X 10 min in 45 degrees C (1X SSC, 0.2% SDS), 3 X 4 min in room temperature (0.1X SSC, 0.1% SDS), and 4 X 4 min in room temperature 0.1X SSC. Slides were dried by centrifugation as before. Fluorescent images of hybridized arrays were acquired immediately at 10 um resolution using ScanArray Express (PerkinElmer). The Cy3 and Cy5 cyanine fluors were excited at 543 nm and 633 nm respectively, and the same laser power (90%) and photomultiplier tube (PMT) settings were used for all slides in a study (PMT 75 Cy3, PMT 63 or 64 Cy5 for head kidney study). Fluorescent intensity data were extracted from TIF images using Imagene 5.5 software (Biodiscovery). Keywords: other

Project description:Prefrontal cortex tissue slices from a cognitively and neurpathologically normal human subject were obtained from the University of Pennsylvania (UPenn) Brain Bank. 300-350 mg grey matter was homogenized in 1.5 ml solution A (0.32 M sucrose, 1mM MgCl2 and 0.1mM CaCl2) with a Teflon pestle. ~100 ?l of the homogenate was saved, solubilized with 1% SDS and clarified by centrifugation. To prepare the [13C6]brain ISTD, 400 mg labeled MouseExpress brain tissue (Cambridge Isotopes, MA) was homogenized in 4 ml buffer A as described above, centrifuged at 1,000 x g for 10 min to clarify, agitated on a rocker at 4�C for 30 min, and centrifuged at 10,000 x g for 20 min. The pellet, a crude membrane fraction, was dissolved in 2 ml 20 mM Tris pH 7.4 with 1% SDS. Total protein in all preparations was quantified with the micro BCA assay (Pierce) and all solutions were supplemented with protease and phosphate inhibitor cocktails (Sigma) as well as 1 mM sodium fluoride and sodium orthovanadate (Sigma). Human cortex homogenate was mixed with the [13C6]brain ISTD (1?g/?l) at a ratio of 2:1(?g/?g) and processed for LC-MS/MS: 40 ?l preparations were heated with lithium dodecyl sulfate (LDS) (Invitrogen) buffer at 95�C for 20 min, separated on a 1.5 mm 4-12% Bis-Tris Gel (Invitrogen), cut into five fractions, chopped into ?2 mm cubes, washed in 200 ?l 50% acetonitrile (ACN) containing 25 mM NH4HCO3, reduced in 300 ?l 10 mM DTT, alkylated in 300 ?l 55 mM iodoacetamide (Sigma), and digested with 80-120 ?l trypsin (.025 ?g/?l) (Promega) overnight at 37�C, so that the amount of trypsin was 1:5 of the total protein to be digested by mass. Peptides were recovered from gel cubes into 200 ?l 50/50 H2O/ACN with 3% formic acid by vortex-mixing and sonication for 20 min each, twice. Samples were then evaporated to a 100 ?l volume, brought to 1ml in H20 with 0.1% formic acid, desalted with Oasis� HLB cartridges (Waters), evaporated almost to completion and suspended in ~ 45?l H2O with 0.1% formic acid, and filtered with 0.22 �m Ultra free-MC filter cartridges (Millipore). LC-data dependant -MS/MS analyses were conducted on a Q Exactive (ThermoFisher Scientific) quadrupole orbi-trap hybrid instrument with an Easy nLC-II (ThermoFisher Scientific) nano-pump/autosampler. 3?l peptide sample (~ 1 ug) was loaded and resolved on a 20 cm x 75 �m proteopepII C18 packed tip column over a 90 min gradient at a flow rate of 350 nL/min, 0-35% mobile phase B (ACN, 0.1 formic acid). A data-dependent top 10 method was used to acquire a 70,000 resolution full scan to trigger ten 17,500 resolution HCD scans. Ions were isolated for MS/MS analysis with a 2.0 Da window on the quadrupole. Average cycle times were 1.2 sec. Each sample was analyzed in triplicate. Raw files from triplicate injections were searched together within Proteome Discoverer 1.3 (ThermoFisher Scientific) using SEQUEST and the human refseq. database (release 47, ftp://ftp.ncbi.nih.gov/refseq/H_sapiens/mRNA_Prot/). Search parameters allowed trypsin to cleave after Lysine and Arginine and have 2 missed cleavages. Precursor ion mass tolerance was set to 15 ppm and fragment ion mass tolerance was 20 mmu. The dynamic modification of methionine (oxidation = 15.995 Da) and lysine (13C6 = 6.020 Da), in addition to the static modification of cysteine (carbamidomethylation = 57.021 Da) was accepted on up to 4 residues per peptide. Within the Proteome Discoverer Software, SILAC pairs were identified using the �2 plex� workflow node, and all peptides were rescored using the Percolator algorithm node. Finally, peptides were filtered at 1% false discovery rate (FDR).

Project description:MicroPoly(A)Pure kits (Ambion) were used to prepare mRNA from P. salmonis-infected and control Atlantic salmon macrophages. Infected and control (24 h incubation) macrophage mRNA samples were subjected to two rounds of amplification using the MessageAmp aRNA kit (Ambion) and manufacturer's instructions. Approximately 400 ng of macrophage mRNA was used as template in the first round of amplification, yielding 8.1 ug of infected macrophage aRNA and 7.8 ug of control macrophage aRNA. Approximately 1 ug of first-round macrophage aRNA was used as template in the second round of amplification, yielding 81.2 ug of infected macrophage aRNA and 83.3 ug of control macrophage aRNA. Infected and control macrophage aRNA samples were visualized on agarose gels to check quality and quantity. Except for the amounts of aRNA and reverse transcription (RT) primer used, macrophage target labeling reactions and microarray hybridizations were identical. Macrophage target syntheses used 5 ug of second-round aRNA and 5 ug of random primers (Roche).
