Function
Brain natriuretic peptide 32. Cardiac hormone that plays a key role in mediating cardio-renal homeostasis (PubMed:1672777, PubMed:17372040, PubMed:1914098, PubMed:9458824). May also function as a paracrine antifibrotic factor in the heart (By similarity). Acts by specifically binding and stimulating NPR1 to produce cGMP, which in turn activates effector proteins that drive various biological responses (PubMed:1672777, PubMed:17349887, PubMed:17372040, PubMed:21098034, PubMed:25339504, PubMed:9458824). Involved in regulating the extracellular fluid volume and maintaining the fluid-electrolyte balance through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion (PubMed:1914098, PubMed:9458824). Binds the clearance receptor NPR3 (PubMed:16870210). NT-proBNP. May affect cardio-renal homeostasis (PubMed:17372040). Able to promote the production of cGMP although its potency is very low compared to brain natriuretic peptide 32 (PubMed:17372040). BNP(3-32). May have a role in cardio-renal homeostasis (PubMed:17372040). Able to promote the production of cGMP (PubMed:17372040).

Notes
The Antibody Pair can be used to quantify Human NT-proBNP. BSA and Azide free antibody pairs include unconjugated capture and detector antibodies suitable for sandwich ELISAs. The antibodies are provided at an approximate concentration of 1 mg/ml as measured by the protein A280 method. The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Both capture and detector antibodies are rabbit monoclonal antibodies delivering consistent, specific, and sensitive results.
For additional information on the performance of the antibody pair, see the equivalent SimpleStep ELISA® Kit (Human NT-proBNP ELISA Kit ab263877), which uses the same antibodies. However, due to differences in their formulation, this antibody pair cannot be used with the consumables provided with our SimpleStep ELISA Kits. Please note that the range provided for the pairs is only an estimation based on the performance of the related product using the same antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody pair in your assay.
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
The pair can be used in variety of assays and platforms including but not limited to:
- Sandwich ELISA
- FRET/TR-FRET/HTRF
- Meso Scale Discovery® (MSD®)
- Bead-based assays
- AlphaLISA®/AlphaScreen®
- DELFIA® immunoassays
- Simoa® and Single Molecule Counting (SMC™) immunoassays
- Multiplex
Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:
- Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- Concentration of ~1 mg/ml as measured by the protein A280 method.
We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.
Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
Please note:
The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

- Activity summary
NT-proBNP known as N-terminal prohormone of brain natriuretic peptide is a non-active prohormone that measures approximately 8.5 kDa in mass. This prohormone emerges from the cleavage of pro-BNP in cardiomyocytes specifically in the heart ventricles. NT-proBNP levels rise in response to ventricular volume expansion and pressure overload therefore serving as an important indicator of cardiac function. Researchers regularly utilize assays like NT-proBNP ELISA and NT-proBNP monoclonal antibodies for detecting its presence in various biological samples.
- Biological function summary
NT-proBNP stands important for cardiovascular homeostasis. It does not participate as part of a complex but plays a role on its own. When released into circulation NT-proBNP functions as an indicator of heart performance indirectly reflecting the activity of the active hormone BNP. Blood vessels dilate under BNP influence reducing systemic vascular resistance and central venous pressure which aids in heart function improvement.
- Pathways
NT-proBNP interacts significantly within the cardiac stress response pathways. It plays a focus within the natriuretic peptide system interacting with proteins such as BNP and ANP that help regulate fluid balance and blood pressure. These components together influence pathways that modulate hemodynamic stress and sodium excretion ensuring cardiovascular stability under stress conditions.
- Associated diseases and disorders
Clinicians use NT-proBNP as a biomarker for heart failure and ischemic heart disease. Elevated levels of NT-proBNP correlate with cardiac stress indicating unmet cardiac workload or myocardial ischemia. In these contexts NT-proBNP serves alongside BNP as an indicator of increased heart strain thereby offering insights into disease progression and patient response to therapeutic interventions.
