Description: The YN1/1.7.4 monoclonal antibody reacts with mouse CD54 (InterCellular Adhesion Molecule-1, ICAM-1), a 90-110 kDa transmembrane glycoprotein expressed by monocytes, lymphocytes, dendritic cells, and endothelial cells. Expression of CD54 is upregulated on activated lymphocytes. Interaction of CD54 with its ligands CD11a and CD11b is important in the inflammatory response. The YN1/1.7.4 monoclonal antibody recognizes a different epitope than the eBioKAT-1 monclonal antibody.
