4°C/-20°C

Human VCAM-1 (CD106), a member of the immunoglobulin superfamily, is a cell surface protein expressed by activated endothelial cells and certain leukocytes such as macrophages. VCAM-1 expression is induced by IL-1beta, IL-4, TNF-alpha and IFN-gamma. VCAM-1 binds to leukocyte integrins VLA-4 and Integrin alpha 4 beta 7.

Sample Type:
Cell culture supernatants, serum, plasma, and tissue

Intended Use:
The Human VCAM-1 BioAssay™ ELISA Kit is an enzyme-linked immunosorbent assay for the quantitative detection of Human VCAM-1 concentrations in cell culture supernatants, serum, plasma, and tissue.

Sensitivity:
60pg/ml

Range:
125-8000pg/ml

Specificity:
Recognizes human VCAM-1.

Sample Volume:
100ul/well

Test Principle:
This assay employs the Sandwich immunoassay technique. An anti-h VCAM-1 monoclonal coating antibody is adsorbed onto microwells. VCAM-1 present in the sample or standard binds to antibodies adsorbed to the microwells. Following incubation unbound sample or standard are removed during a wash step. a Biotinylated anti-h VCAM-1 antibody is added and binds to VCAM-1 captured by the first antibody. Following incubation unbound Biotinylated anti-h VCAM-1 antibody is removed during a wash step. A Streptavidin-HRP is added and binds to Biotinylated anti-h VCAM-1 antibody. Following incubation unbound Streptavidin-HRP is removed during a wash step. A colored product is formed in proportion to the amount of VCAM-1 present in the sample. The reaction is terminated by addition of acid and absorbance is measured at 450nm. A standard curve is prepared from seven VCAM-1 standard dilutions and VCAM-1 sample concentration determined.
