特徴

• Sample Type:Serum, plasma and tissue homogenates
• Intended Use:For the quantitative determination of human platelet-derived growth factor AB (PDGF-AB) concentrations in serum, plasma and tissue homogenates.
• Sensitivity:7.8pg/ml
• Range:31.25-2000pg/ml
• Specificity:This assay has high sensitivity and excellent specificity for detection of human PDGF-AB. No significant cross-reactivity or interference between human PDGF-AB and analogues was observed.
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for PDGF-AB has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any PDGF-AB present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PDGF-AB 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 PDGF-AB bound in the initial step. The color development is stopped and the intensity of the color is measured.
