Natriuretic peptides A, CDD-ANF, Cardiodilatin, CDD, Cardiodilatin-related peptide, CDP, N-terminal proatrial natriuretic peptide, ANP, PND.

Natriuretic Peptide A is a part of the natriuretic peptide family and is involved  in cardiovascular homeostasis through regulation of natriuresis, diuresis, and vasodilation. NPPA is synthesized as a great precursor which releases a peptide from the N-terminus with similarity to vasoactive peptide, cardiodilatin, and another peptide from the C-terminus with natriuretic-diuretic activity. In female pregnancy, NPPA is promoting trophoblast invasion and spiral artery remodeling in uterus.

利钠肽 A 是利钠肽家族的一部分，通过调节利钠、利尿和血管舒张参与心血管稳态。 NPPA 被合成为一种伟大的前体，它从 N 端释放一种与血管活性肽、心脏扩张肽相似的肽，并从 C 端释放另一种具有利钠利尿活性的肽。 在女性妊娠期，NPPA 促进子宫内滋养层侵袭和螺旋动脉重塑。

NPPA Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 106 amino acids including an 8 a.a N-terminal His tag. The total molecular mass is 11.7kDa .

在大肠杆菌中产生的 NPPA Human Recombinant 是一种单一的、非糖基化的多肽链，包含 106 个氨基酸，包括一个 8 个氨基酸的 N 端 His 标签。 总分子量为11.7kDa。

Escherichia Coli.

Filtered White lyophilized powder.

NPPA filtered and lyophilized from 0.5mg/ml in 20 mM Tris buffer, 50 mM NaCl and 5% w/v trehalosa, pH 7.5.

It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. NPPA is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

建议加入去离子水配制约 0.5mg/ml 的工作原液，让冻干颗粒完全溶解。 NPPA 不是无菌的！ 在细胞培养中使用之前，请用适当的无菌过滤器过滤产品。

Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

将冻干蛋白储存在 -20°C。 重组后分装产品以避免重复的冷冻/解冻循环。 重组蛋白可在 4°C 下保存一段时间； 在 4°C 下两周后它没有显示任何变化。

Greater than 95.0% as determined by -PAGE.
