Synonyms

NT-proBNP,; N-terminal prohormone of brain natriuretic peptide,;

Intended use

This immunoassay kit allows for thein vitro quantitative determination ofhuman N-terminal prohormone of brain natriuretic peptide,NT-proBNP concentrations in serum, Plasma, tissue homogenates and Cell culture supernates and Other biological fluids.

Test principle

The microtiter plate provided in this kit has been pre-coated with anantibody specific to NT-proBNP. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific forNT-proBNPand Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain NT-proBNP, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of NT-proBNPin the samples is then determined by comparing the O.D. of the samples to the standard curve.
