Recombinant Human BNP Protein Summary

A single, non-glycosylated biologically active polypeptide chain corresponding to 32 residues of NPPB.

Source: E. coli


Novus' biologically active proteins are stringently purified to provide only the safest and most highly effective proteins available. This protein was expressed in E. coli, purified by HPLC, QC tested by SDS-PAGE and Western Blot and validated on appropriate cell lines for bioactivity. All HPLC and bioactivity data is provided for your assurance.
E. coli
Protein/Peptide Type
Recombinant Protein
> 97 % pure by SDS-PAGE and HPLC
Endotoxin Note
Less than 1 EU/ug of endotoxin as determined by LAL method.


Theoretical MW
3.5 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

Store at -20C. Avoid freeze-thaw cycles.
Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4.
No Preservative
> 97 % pure by SDS-PAGE and HPLC
Reconstitution Instructions
Recommended to centrifuge prior to opening. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/mL. Apportion stock solutions into working aliquots and store at <-20C.


This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

Alternate Names for Recombinant Human BNP Protein

  • BNF
  • BNP
  • brain type natriuretic peptide
  • Gamma-brain natriuretic peptide
  • natriuretic peptide B
  • natriuretic peptide precursor B
  • natriuretic peptides B
  • natriuretic protein
  • NPPB


Brain Natriuretic Peptide is encoded by the BNP gene located on the Chr.1 in humans. It is firstly discovered in the porcine brain and given this name, but the protein is mainly expressed in the cardiac ventricles in human body after the excessive stretching of cardiomyocytes. The gene expresses a 134 a.a. sequence which contains a 1-26 a.a. signal peptide and 27-134 a.a. Natriuretic peptides B, and the BNP is the 32 a.a. C-terminus of natriuretic peptides B. The BNP can be cleaved in 16 chains and the rHuBNP is 1-32. BNP acts as a cardiac hormone with a variety of functions including natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Additionnaly, it plays a key role in cardiovascular homeostasis, helps restore the body's salt and water balance and improves heart function.
