Amino Acid Sequence Determination of Human S100A12 (P6, Calgranulin C, CGRP, CAAF1) by Tandem Mass Spectrometry

S100A12 has been isolated from human neutrophils. The molecular weight and the amino acid sequence of S100A12 was determined by electrospray-mass spectrometry, tandem mass spectrometry and Edman microsequence analysis. Interestingly, a sequence comparison of S100A12 with all known human S100 protein...

Zusammenfassung:S100A12 has been isolated from human neutrophils. The molecular weight and the amino acid sequence of S100A12 was determined by electrospray-mass spectrometry, tandem mass spectrometry and Edman microsequence analysis. Interestingly, a sequence comparison of S100A12 with all known human S100 proteins revealed that S100A12 is the most divergent of the S100 proteins.
