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.

利钠肽前体 B 作为一种心脏激素，具有多种生物作用，包括利尿钠、利尿、血管舒张以及抑制肾素和醛固酮分泌。 它被认为在心血管稳态中起关键作用。 帮助恢复身体的盐分和水分平衡。 改善心脏功能。

B-type Natriuretic Peptide Recombinant Human produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 32 amino acids and having a molecular mass of 3,500 Dalton. NPPB is purified by proprietary chromatographic techniques.

在大肠杆菌中产生的 B 型利钠肽重组人是单条非糖基化多肽链，含有 32 个氨基酸，分子量为 3,500 道尔顿。 NPPB 通过专有的色谱技术进行纯化。

Escherichia Coli.

Sterile Filtered White lyophilized powder.

Natriuretic Peptide Precursor B was lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.

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.

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 .
Please prevent freeze-thaw cycles.

冻干的 B 型利钠肽虽然在室温下可稳定保存 3 周，但应在 -18°C 以下干燥储存。 复溶后，NPPB 应在 4°C 下储存 2-7 天，以备将来在 -18°C 以下使用。
对于长期储存，建议添加载体蛋白。
请防止冻融循环。

Greater than 97.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.
