The Human ICAM-1/CD54 (intercellular adhesion molecule 1) ELISA quantitates ICAM-1 in serum, plasma and other biological fluids.
原理方法
The Human intercellular adhesion molecule 1 (ICAM-1/CD54) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of intercellular adhesion molecule 1 (ICAM-1/CD54) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to intercellular adhesion molecule 1 (ICAM-1/CD54). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of intercellular adhesion molecule 1 (ICAM-1/CD54) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

ICAM-1 (CD54) is an 85-110 kDa single-chain type 1 integral membrane glycoprotein with an extracellular domain of five immunoglobulin superfamily repeats, a transmembrane region and a cytoplasmic domain. ICAM-1 has 7 potential N-linked glycosylation sites and shares considerable amino acid sequence homology with ICAM-3 (CD50) and ICAM-2 (CD102). ICAM-1 binds to integrins of type CD11a/CD18 (leukocyte adhesion molecule, LFA-1), or CD11b/CD18 (Mac-1) and is exploited by Rhinovirus as a receptor. ICAM-1 is expressed by activated endothelial cells and detected on epithelial cells, fibroblasts, chondrocytes, B lymphocytes, T lymphocytes (low), monocytes, macrophages, dendritic cells and neutrophils, with lower levels that increase upon inflammation. ICAM-1 is also detected in some carcinoma and melanoma cells. Soluble ICAM-1 is detectable in the plasma and is elevated in patients with various inflammatory syndromes.
