特徴

• This gene is a member of the Ig superfamily and encodes a cell surface sialoglycoprotein expressed by cytokine-activated endothelium. This type I membrane protein mediates leukocyte-endothelial cell adhesion and signal transduction, and may play a role in the development of artherosclerosis and rheumatoid arthritis. Two alternatively spliced transcripts encoding different isoforms have been described for this gene.
• Sample Type:Serum, plasma and tissue homogenates
• Intended Use:For the quantitative determination of human vascular cell adhesion molecule 1 (VCAM-1) concentrations in serum, plasma and tissue homogenates.
• Sensitivity:0.611ng/ml
• Range:1.563-100ng/ml
• Specificity:This assay has high sensitivity and excellent specificity for detection of human VCAM-1. No significant cross-reactivity or interference between human VCAM-1 and analogues was observed.
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. An antibody specific for VCAM-1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any VCAM-1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VCAM-1 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of VCAM-1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
