The Association of Biomolecular Resource Facilities' Proteomics Standards Research Group said this week that it has extended the deadline to submit results for its 2010 phosphopeptide study to Jan. 15.
The study focuses on the ability of core facilities to identify the phosphorylation sites of multiple phosphopeptides present in a single sample. Each laboratory will be able to evaluate its capabilities and approaches for detecting phosphopeptides and identifying phosphorylation sites.
The study also will be a first step to develop a phosphopeptide standard that more closely resembles a "real life" sample, the group said in its original announcement in the fall.
Results from the study will be presented at ABRF's annual meeting in March.
