The HA58 monoclonal antibody specifically binds to CD54 which is also known as ICAM-1 (intracellular adhesion molecule-1). CD54 is an 85-110 kDa type I transmembrane glycoprotein that belongs to the immunoglobulin supergene family
A soluble form of CD54 can also be found in biological fluids
CD54 is expressed on endothelial cells and both resting (weak) and activated (moderate) lymphocytes and monocytes
CD54 is a ligand for LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18)
The CD54 adhesion molecule plays roles in inflammatory and immune responses and neoplasia
This antibody (NA/LE format) blocks the mixed-lymphocyte reaction (MLR) and the purified format is suitable for staining acetone-fixed, frozen tissue sections.
