Two ABRF Research Groups Announce Studies for 2010, While Two Others Extend Sample-Request Deadlines

This story originally ran on Oct. 8.

Two research groups of the Association of Biomolecular Resource Facilities this week announced their studies for 2010, while two other groups have extended their deadlines for participation in their studies.

The Proteomics Standards Research Group is conducting a study to test the ability of core facilities to identify multiple phosphopeptides present in a single sample and to determine their phosphorylation sites.

In its announcement, the group said the study "represents the first step in developing a phosphopeptide standard that more closely resembles a 'real life' sample."

Participating labs will receive a mixture containing a tryptic digest of six proteins, all of which will contain at least one phosphorylated residue. The peptides will be present in sufficient quantities to allow various strategies to be used.

Participants will be asked to complete an online survey and submit their supporting data.

The study is open to ABRF members and non-members, though priority will be given to members due to the limited number of samples. Vendors are also welcome to participate.

Requests for samples should be e-mailed to [email protected] prior to the end of the business day, Oct. 16. The words "Sample request" should be included in the subject line. The samples are expected to be distributed on Oct. 19. Data should be submitted by Dec. 11.

Also, the newly formed Metabolomics Research Group said it is conducting a survey to collect data on the current use of metabolomics technologies in core facilities.

"Questions are designed to elicit responses concerning the current level of interest in the field of metabolomics, and for those already offering a metabolomics service to find out what instrumentation is used, types of application, etc.," the group said in its announcement.

The survey is available here.

Meanwhile, the Protein Sequencing Research Group has extended its deadline for requesting a sample for its 2010 study to Oct. 16.

This year's study will explore traditional and alternative methods for obtaining N-terminal information on a complex mixture. Requests for a sample should be e-mailed to [email protected]

And the Glycoprotein Research Group also extended its deadline for a sample request, to Oct. 20. Requests should be sent to [email protected]

This year's study will investigate different approaches for determining the relative differences in N glycosylation between three similar glycoprotein samples [See PM 09/17/09].

Results from all ABRF research groups will be presented at the organization's annual meeting in March in Sacramento, Calif.
