The antibody detects endogenous level of ICAM-1 only when phosphorylated at tyrosine 512.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific phosphopeptide. The antibody against non-phosphopeptide was removedby chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
Peptide sequence around phosphorylation site of pTyr512 (K-K-Y (p) -R-L) derived from Human ICAM-1. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.
ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin a-L/beta-2). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus.
