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 in 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 a number of 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.

Human Cells

A DNA sequence encoding the human ICAM1 (NP_000192.2) extracellular domain (Met 1-Glu 480) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Human

The recombinant human ICAM1/Fc is a disulfide-linked homodimer. The reduced monomer consists of 700 amino acids and has a predicted molecular mass of 77.4 kDa. As a result of glycosylation, the apparent molecular mass of rh ICAM1/Fc monomer migrates with an apparent molecular mass of 100-110 kDa in SDS-PAGE under reducing conditions.

> 95 % as determined by SDS-PAGE

Measured by the ability of the immobilized protein to support the adhesion of PMA stimulated HSB2 human peripheral blood acute lymphoblastic leukemia cells.
When 5 x 10E4 cells/well are added to Recombinant Human ICAM-1/CD54 coated plates (12.5 μg/mL with 100 μL/well), >40% cells will adhere after 1 hour incubation at 37℃.
