25x Biotin-detection Ab (human sICAM-1 Biotin-dAb). PN: A1132638B. One vial containing 100 µL of biotinylated anti-human sICAM-1.

Lyophilized Standard Mix-Human Group 5 Panel B, 10-Plex. PN: HG50010. One vial containing lyophilized recombinant human sRANKL, sEndoglin, sVCAM-1, sE-selectin, sCD95L, sICAM-1, sCD25, sCD14, sTNFRI, and sCD40L.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human ICAM-1/sCD54. Can be multiplexed with other analytes in Human Group 5.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

ICAM-1 (Intercellular Adhesion Molecule 1) also known as CD54 is a cell surface glycoprotein which is typically expressed on endothelial cells and cells of the immune system. It binds to integrins of type CD11a / CD18, or CD11b / CD18 and is also exploited by rhinovirus as a receptor. It is a type of intercellular adhesion molecule continuously present in low concentrations in the membranes of leukocytes and endothelial cells. Upon cytokine stimulation, the concentrations greatly increase. ICAM-1 can be induced by interleukin-1 (IL-1) and tumor necrosis factor (TNF) and is expressed by the vascular endothelium, macrophages, and lymphocytes.  ICAM-1 has been implicated in subarachnoid hemorrhage (SAH). Levels of ICAM-1 are shown to be significantly elevated in patients with SAH over control subjects in many studies. While ICAM-1 has not been shown to be directly correlated with cerebral vasospasm, a secondary symptom that affects 70% of SAH patients, treatment with anti-ICAM-1 reduced the severity of vasospasm.  ICAM-1 expressed by respiratory epithelial cells is also the binding site for rhinovirus, the causative agent of most common colds. ICAM-1 has an important role in ocular allergies recruiting pro-inflammatory lymphocytes and mast cells promoting a type I hypersensitivity reaction.
