Icam1

Recombinant extracellular domain of mouse ICAM1 (NP_034623.1) (Met 1-Asn 485) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Intercellular adhesion molecule-1 (ICAM-1, or CD54) is a 90 kDa member of the immunoglobulin (Ig) superfamily and is critical for the firm arrest and transmigration of leukocytes out of blood vessels and into tissues. ICAM-1 is constitutively present on endothelial cells, but its expression is increased by proinflammatory cytokines. The endothelial expression of ICAM-1 is increased in atherosclerotic and transplant-associated atherosclerotic tissue and animal models of atherosclerosis. Additionally, ICAM-1 has been implicated in the progression of autoimmune diseases. ICAM-1 is a ligand for LFA-1(integrin). When activated, leukocytes bind to endothelial cells via ICAM-1/LFA-1 interaction and then transmigrate into tissues. Presence with heavy glycosylation and other structural characteristics, ICAM-1 possesses binding sites for some immune-associated ligands and serves as the binding site for entry of the major group of human Rhinovirus (HRV) into various cell types. ICAM-1 also becomes known for its affinity for Plasmodium falciparum-infected erythrocytes (PFIE), providing more of a role in infectious disease. Previous studies have shown that ICAM-1 is involved in inflammatory reactions and that a defect in ICAM-1 gene inhibits allergic contact hypersensitivity.

Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.

The recombinant mouse ICAM1/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 706 amino acids and has a predicted molecular mass of 78.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm ICAM1/Fc monomer is approximately 120-130 kDa due to glycosylation.
