This assay kit uses a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of NT-ProBNP in porcine serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Sensitivity: 43.8pg/ml Range: 123.5-10,000pg/ml Specificity: This assay has high sensitivity and excellent specificity for detection of N-Terminal Pro-Brain Natriuretic Peptide (NT-ProBNP). No significant cross-reactivity or interference between N-Terminal Pro-Brain Natriuretic Peptide (NT-ProBNP) and analogues was observed. Precision: Intra-Assay: CV<10% Inter-Assay: CV<12% Test Principle: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to NT-ProBNP has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled NT-ProBNP and unlabeled NT-ProBNP (Standards or samples) with the pre-coated antibody specific to NT-ProBNP. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of NT-ProBNP in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of NT-ProBNP in the sample. Kit Components: 96-well strip plate, 1x Plate Standard, 2x vial Detection Reagent A, 1*120ul Detection Reagent B, 1*120ul TMB Substrate, 1*9ml Wash Buffer (30X), 1*20ml Standard Diluent, 1*20ml Assay Diluent A, 1*12ml Assay Diluent B, 1*12ml Stop Solution, 1x6ml Storage and Stability: Store all components at 4C. Stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
