N-terminal B-type Natriuretic Peptide Determination Kit

Product Name: N-terminal pro-B-type natriuretic peptide (Fluorescence Immunoassay)

Abbreviation: NT-proBNP



For the quantification of N-terminal pro-brain natriuretic peptides in human serum, plasma or whole blood.

Used for auxiliary diagnosis of heart failure in clinic.



Take the sample to the strip, The NT-proBNP in the specimen binds to the antibody coated with the fluorescent particles coated on the glass fiber to form a fluorescent particle-antibody-antigen complex. The immune complex is further chromatographed along the nitrocellulose membrane to the detection zone (T), and combined with the pre-coated mouse anti-NT-proBNP monoclonal antibody, the fluorescence intensity is proportional to the NT-proBNP content in the sample, and the remaining Fluorescent antibody particles were chromatographed into the control region (C) and bound to pre-coated goat anti-mouse IgG.
