A specific and sensitive in vitro ELISA assay and diagnostic test kit is disclosed for determining levels of NT-proBNP protein in a variety of bodily fluids, non-limiting examples of which are blood, serum, plasma, urine and the like. The NT-proBNP ELISA assay test employs the sandwich ELISA technique to measure circulating NT-proBNP in human plasma. In order to obtain antibodies with specific binding properties for targeted amino acid sequences within human proBNP, recombinant human proBNP (or rhproBNP) was expressed and purified for use as an immunogen. Polyclonal antibodies (PAb) to specific amino acid sequences were subsequently purified from goat serum by sequential affinity purification. Recombinant human NT-proBNP (or rhNT-proBNP) was expressed and purified in order to obtain material for use in calibration of a quantitative method for measurement of human NT-proBNP.

L'invention concerne un dosage ELISA in vitro spécifique et sensible et un nécessaire de diagnostic permettant de mesurer les niveaux du peptide NT-proBNP dans divers liquides biologiques, y compris, sans en exclure d'autres, le sang, le sérum, le plasma, l'urine et analogue. Ce dosage ELISA NT-proBNP utilise la technique ELISA de type sandwich pour mesurer les NT-proBNP circulant dans le plasma humain. Pour obtenir des anticorps avec des propriétés de fixation spécifiques pour des séquences d'acides aminés cibles dans le proBNP humain, un proBNP humain recombiné (ou rhproBNP) a été exprimé et purifié pour être utilisé comme un immunogène. Ensuite, des anticorps polyclonaux (PAb) de séquences d'acides aminés spécifiques ont été purifiés à partir du sérum de chèvre par purification par affinité séquentielle. Le NT-proBNP humain recombiné (ou rhNT-proBNP) a été exprimé et purifié pour fournir un matériel pouvant être utilisé pour le calibrage d'une méthode quantitative de mesure du NT-proBNP humain.
