Gain New Insights Into Human Spermatogenesis with this “Click & Easy” OneOmics Workflow

Dec 4, 2015 | Blogs, Life Science Research, Proteomics | 0 comments

A recent webcast by Charles Pineau, Director of Protim, IRSET, Rennes, France, demonstrates how you can use the OneOmics™ Platform as a “Click & Easy” workflow for integrating next-generation proteomics (NGP) data with next-generation sequencing (NGS) data. Dr. Pineau and his colleagues are interested in gaining new insights into human spermatogenesis and understanding the dialogue between germ cells and somatic cells. In previous research using rat samples, over 1400 unannotated transcripts were identified. Subsequent proteogenomic studies then showed that some of those transcripts encoded for novel proteins. The data analysis for that research was performed using the open source EMBOSS suite of tools. 

In the current study, the researchers were interested in analyzing human samples and developing a more simplified workflow for data analysis. Using the SCIEX TripleTOF® 6600, and the Illumina HiSeq 2500, over 1100 new potential transcripts were identified with more than 2 peptides at FDR < 1%. The OneOmics Platform was used for data processing and analysis. Compared with the previous open source EMBOSS suite of tools used in the rat studies, the OneOmics Platform was about 75x faster. Additionally, another major benefit using the OneOmics Platform was the relative ease with which the data could be analyzed compared with the previous workflow which required extensive user customization by writing scripts and formatting files. This enabled the researchers to focus on the biology rather than the complications associated with formatting datasets and transformation of files. Ongoing studies are taking a subset of candidates and validating them using MRM studies, qPCR, and immunohistochemistry.

ProteinPilot phosphopeptide library and DIA-NN

I have prepared a spectral library for a phosphopeptide enriched sample and I am generating my SWATH samples from similarly enriched samples. The problem is that when I use DIA-NN for the retention time alignment and quant, it doesn’t recognise the terminology of the spectral library annotated by ProteinPilot. DIA-NN recognises Unimod:21 for phosphorylation, but PP uses phospho(Tyr) etc. Other than changing the data dictionary to get around the mismatch, anyone have any suggestions for how I might resolve this? Thank you, Roz

Current proteomics software compatibility for ZenoTOF 7600 system

Below is a summary of various other software packages that are useful for processing proteomics data from the ZenoTOF 7600 system.  Note this list is not comprehensive and only covers the tools we have lightly tested to date. Acquisition Type Software Files needed...

Sequential processing of multiple data-files in ProteinPilot

I would like to use ProteinPilot 5.0.2 to process data-sets containing 16 wiff files acquired from fractionated peptides on a 6600 TripleTOF. A Precision T7910 workstation struggles to process four files in parallel and I would like to be able to queue sequential processing of individual files overnight. I currently use the ‘LC ‘ tab to load and process individual data-files but this leads to parallel processing. Is it possible to generate 16 .group files sequentially?
