                                Introduction
                                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.
 
                                Description
                                B-type Natriuretic Peptide Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 32 amino acids and having a molecular mass of 3464 Dalton. 
NPPB is purified by proprietary chromatographic techniques.
                                Source
                                Escherichia Coli.
                                Physical Appearance
                                Sterile Filtered White lyophilized (freeze-dried) powder.
                                Formulation
                                Natriuretic Peptide Precursor B was lyophilized from 0.4ml PBS buffer containing 20mM phosphate buffer and 0.6mM sodium chloride.
                                Solubility
                                It is recommended to reconstitute the lyophilized B-type Natriuretic Peptide in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
                                Stability
                                Lyophilized B-type Natriuretic Peptide although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution NPPB should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
