特徴

• Sample Type:Serum, plasma and cell culture supernates
• Intended Use:For the quantitative determination of human transforming growth factor beta 1 (TGF-b1) concentrations in serum, plasma and cell culture supernates.
• Sensitivity:0.747ng/ml
• Range:0.78-50ng/ml
• Specificity:This assay has high sensitivity and excellent specificity for detection of human TGF-b1. No significant cross-reactivity or interference between human TGF-b1 and analogues was observed.
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for TGF-b1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TGF-b1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TGF-b1 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 TGF-b1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
