Product Summary for Human ICAM-1/CD54 Allele-specific Quantikine ELISA Kit
The Quantikine Human sICAM-1 immunoassay is a 2.0 hour solid phase ELISA designed to measure sICAM-1 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human sICAM-1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human sICAM-1 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring sICAM-1.

Background: ICAM-1/CD54
ICAM-1 (intercellular adhesion molecule-1), also known as CD54, is a transmembrane protein that is upregulated on endothelial and epithelial cells at sites of inflammation. It mediates the vascular adhesion and paracellular migration of leukocytes expressing activated LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18). It also binds several non-integrin ligands including CD43/Sialophorin, Fibrinogen, Hyaluronan, rhinoviruses, and Plasmodium falciparum-infected erythrocytes. Soluble ICAM-1 promotes angiogenesis and serves an indicator of vascular endothelial cell activation or damage. Elevated levels of soluble ICAM-1 are associated with cardiovascular disease, type 2 diabetes, organ transplant dysfunction, oxidant stress, increased abdominal fat mass, hypertension, liver disease, certain malignancies, and cerebral malaria.
