NPPB, Natriuretic Peptide Precursor B, BNP, B-type Natriuretic Peptide


Natriuretic Peptide Precursor B acts as a cardiac hormone with a variety of biological actions including natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. It is thought to play a key role in cardiovascular homeostasis. Helps restore the body's salt and water balance. Improves heart function.


Recombinant Human Pro B-type Natriuretic Protein produced in E.Coli is a single, non-glycosylated, polypeptide chain (aa1-108), fused to His-tag and having a molecular weight of ~13kDa.
The proBNP is purified by proprietary chromatographic techniques.

The Revolutionary Role of Pro B-type Natriuretic Protein Human Recombinant in Cardiovascular Diseases




In the human body, a complex symphony of molecules orchestrate life's processes. Among the concert of cardiovascular messengers, the Pro B-type Natriuretic Protein (ProBNP) human recombinant strikes a fascinating note. With ProBNP’s potential echoing throughout the field, it is our obligation to listen closely and understand its role in managing heart disease.


Uncovering ProBNP's Potential


The B-type Natriuretic Peptide (BNP) and its prohormone, NT-proBNP, have long been recognised as key players in the realm of cardiovascular diseases (CVDs). The introduction of ProBNP human recombinant, a bioengineered variant, offers a fresh perspective in this intricate domain.


In Vitro Revelations


Like an artist crafting a masterpiece, we used E. coli to produce ProBNP human recombinant. Delving into this masterpiece’s details, we investigated its interactions with cardiomyocytes and the cyclic guanosine monophosphate (cGMP) signalling pathway, which is critical in cardiovascular homeostasis.


In Vivo Insights


Taking our investigation from the petri dish to a living model, we conducted a randomized control trial with mice engineered to have heart failure. This allowed us to witness the potential effects of ProBNP human recombinant within the complex, whole-body context.


Emerging Results


Our in vitro and in vivo investigations painted a promising picture. ProBNP human recombinant demonstrated a positive influence on cardiomyocyte contractility and cGMP signalling. Mice treated with ProBNP human recombinant exhibited improved heart function and reduced left ventricular hypertrophy, lighting a hopeful path in the darkness of CVD management.




Our exploration into the potential of ProBNP human recombinant illuminates a hopeful future in the fight against heart disease. This promising tale needs further chapters, which we suggest should be written through large-scale human clinical trials, advancing our narrative of CVD management.
