Protein Sequence Research Committee



The Protein Sequence Research Committee has prepared, characterized, and distributed this year's test sample, ABRF-95SEQ. This sample is a protein and contains standard amino acids including cysteine and tryptophan, which were the focus of last year's study. In addition, when designing ABRF-95SEQ, the committee deliberately introduced some sequence heterogeneity within the first ten residues. The primary objective of this year's study is to determine how far this sample can be sequenced. Therefore, we encourage all study participants to assign as much sequence for this sample as they can, using the same criteria for sequence accuracy as they usually would for a sample submitted to their facilities for analysis. Please make every effort to analyze the sample, and return the first twenty-five chromatograms, the calibration standard chromatogram, the data reporting sheets, and the short questionnaire using the return mailing label sent with the sample.

Because the supply of this sample was limited, ABRF-95SEQ was mailed during the first week of February only to facility directors listing protein sequencing as a facility service in their ABRF membership profiles. To all other facility directors, the committee sent a letter announcing the study and a form for ordering the sample from the committee. If you are a member (facility director) of ABRF and wish to receive ABRF-95SEQ, please contact Jay Gambee at (503) 221-3445, Fax: (503) 221-3451.
