Background | Intercellular adhesion molecule-1 (ICAM-1, or CD54) is a 9 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. |
Description | A DNA sequence encoding the human ICAM1 (NP_000192.2) extracellular domain (Met 1-Glu 480) with five amino acids (DDDDK) at the C-terminus was expressed and purified. |
Source | HEK293 |
Predicted N Terminal | Gln 28 |
AA Sequence | Met 1-Glu 480 |
Molecular Weight | The recombinant human ICAM1 consists of 459 a.a. and has a predicted molecular mass of 51 kDa. As a result of glycosylation, it migrates with an apparent molecular mass of 70-80 kDa in SDS-PAGE under reducing conditions. |
Purity | >95% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | Please contact us for detailed information |
Formulation | Lyophilized from sterile Tris 50mM, NaCl 100mM, pH 8.0. |
Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
Usage | For Research Use Only |
Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
