COMPOSITIONS AND METHODS FOR ANALYZING HISTIDINE PHOSPHORYLATION

摘要

A peptide of the general structure: Z-W-Y, wherein Z and Y are independently a one to eight amino acid sequence wherein the amino acids are selected from glycine and alanine and W is a non-hydrolyzable pHis analogue. Such peptides can be used to produce sequence-independent anti-phosphohistidine antibodies. Also provided is a composition comprising antibodies that specifically bind to a peptide comprising a phosphohistidine (or a non-hydrolyzable pHis analogue) but fail to specifically bind to an identical peptide containing histidine instead of phosphohistidine.
