特徴

• Sample Type:Serum, plasma and tissue homogenates
• Intended Use:For the quantitative determination of human N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations in serum, plasma and tissue homogenates.
• Sensitivity:0.216ng/ml
• Range:0.313-20ng/ml
• Specificity:This assay has high sensitivity and excellent specificity for detection of human NT-proBNP. No significant cross-reactivity or interference between human NT-proBNP and analogues was observed.
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. An antibody specific for NT-proBNP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any NT-proBNP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for NT-proBNP 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 NT-proBNP bound in the initial step. The color development is stopped and the intensity of the color is measured.
