Samples Available for ABRF sPRG 2013 Study

Premium

The Proteomics Standards Research Group of the Association of Biomolecular Resource Facilities has announced the availability of samples for its 2013 study.

The study will test the ability of core facilities to determine relative quantitation of up to 1,000 heavy/light peptide pairs in a single sample.

Participating labs will receive a vial with a lyophilized mixture of stable isotope labeled synthetic peptides in a tryptic digest of HEK293 cells. Labs will have to analyze the samples in triplicate via LC-MS and report peak area ratios and coefficients in variation.

The study is open both to ABRF members and non-members, but priority for samples will be given to members. Each lab completing the entire study will receive an aliquot of the 1000 labeled peptides for their own use.

Requests for samples must be submitted by email to [email protected] by end of day Sept. 30. Results should be returned by Oct. 11 and will be presented at the 2014 ABRF meeting.
