Project description:Top-down proteomics of venom protein of venom-gland organoids aspidelaps. Samples were extracted with MilliQ water and proteins reduced with TCEP before top-down LC-MS/MS analysis.

Run 2
Project description:Venom proteomics analysis of Walterinnesia aegyptia and Walterinnesia morgani. For top-down analysis, venom samples were reduced with TCEP and measured via HPLC-MS/MS (Q-Exactive and LTQ-Orbitrap XL).
Project description:Top-down and bottom-up protein analysis of venom and saliva of solenodon. Venom and saliva was separated by HPLC and either directly analysis by HR FT MS/MS (Top-down) or further decomplexed by SDS-PAGE followed by in-gel trypsine digestion and HR LC-MS/MS analysis (bottom-up, Venom only). For shotgun bottom-up comparison of venom and saliva proteins, samples were directly reduced, alkylated, digested with trypsin and measured by HPLC-MS/MS. Additional bottom-up analysis was performed from bioactivity guided fractionation experiments.
Project description:Top-down Proteomics of Venom from Naja haje from the Berlin Zoo. 4 technical replicates from TCEP reduced crude venom and 1 replicate from native venom.
Project description:Diachasmimorpha longicaudata parasitoid wasps carry a symbiotic poxvirus, known as DlEPV, within the female wasp venom gland. We sequenced RNA from venom gland tissue to identify DlEPV orthologs for 3 conserved poxvirus core genes. The DlEPV ORFs identified from this transcriptome were used to design primers for downstream RT-qPCR analysis and RNAi knockdown experiments.
Project description:Genus-wide proteomics analysis of cobra (Naja) venoms. For top-down analysis, venom samples were reduced with TCEP and measured via HPLC-MS/MS (Q-Exactive) . Spectrum-Protein matching was performed with TopPic1.1 against a genus wide translated transcriptome database and NCBI protein entries from the najas.
For bottom-up analysis, HPLC separated fraction of venom were dried down, reduced with triethylphosphine and alkylated with 2-iodoethanol. HPLC-MS/MS experiments were performed on normalflow UHPLC-QTOF system (AB Sciex 5600 TripleTOF). Data analysis (PSM) was performed ProteinPilot version 4.0 and the transcriptome derived protein sequence database.
