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,vasorelaxation,diuresis and inhibition of renin and aldosterone secretion. BNP plays a key role in cardiovascular homeostasis. BNP also helps restore the body’s salt and water balance andimproves heart function.

利钠肽前体 B 作为一种心脏激素，具有多种生物作用，包括利钠、血管舒张、利尿以及抑制肾素和醛固酮的分泌。 BNP 在心血管稳态中起关键作用。 BNP 还有助于恢复身体的盐和水平衡并改善心脏功能。

NT-Pro-B-type Natriuretic Protein Human Recombinant produced in E.Coli is a non-glycosylated polypeptide chain containing 76 amino acid and having a molecular mass of approximately 8.5kDa.

NT-proBNP is purified by proprietary chromatographic techniques.

NT-Pro-B-type Natriuretic Protein Human Recombinant 在大肠杆菌中产生，是一种非糖基化多肽链，含有 76 个氨基酸，分子量约为 8.5kDa。

NT-proBNP 通过专有的色谱技术进行纯化。

Escherichia Coli.

Sterile Filtered White lyophilized powder.

Lyophilized from a 0.2μm filtered concentrated solution in 20mM Tris-HCl, pH 8.0 and 150mM NaCl.

从 20mM Tris-HCl、pH 8.0 和 150mM NaCl 中的 0.2μm 过滤浓缩溶液冻干。

It is recommended to reconstitute the lyophilized NT-Pro-B-type Natriuretic Protein in sterile 18MΩ-cm H₂O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

建议将冻干的 NT-Pro-B 型利钠蛋白在不低于 100µg/ml 的无菌 18MΩ-cm H2O 中复溶，然后可以进一步稀释成其他水溶液。

Lyophilized NT-proBNP although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution NT-Pro-B-type Natriuretic Protein should be stored at 4°C between 2-7 days and for future use below -18°C.

冻干的 NT-proBNP 虽然在室温下可稳定保存 3 周，但应在 -18°C 以下干燥储存。 重构后，NT-Pro-B 型利尿钠蛋白应在 4°C 下储存 2-7 天，以备将来在 -18°C 以下使用。

Please prevent freeze-thaw cycles.

Greater than 98.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.
