KLKB1 重组蛋白, Rat (E. coli, His)

KLKB1 Protein, Rat, Recombinant (E. coli, His)

产品编号 TMPH-03351

The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin. KLKB1 Protein, Rat, Recombinant (E. coli, His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 31.8 kDa and the accession number is P14272.

常见问题解答

问抑制剂母液的储存方式？

答母液配置完成后，一般储存于 -80℃，可以存 1 年以上。建议多分装几管，避免反复冻融，常用的存于 4 度，可放一周以上。

问抑制剂加 DMSO 配成母液之后，能否放在常温的环境保存1周？

答不建议这么做，母液配置好分装保存，建议存于 -20℃ 或 -80℃，尽量避免反复冻融。如果您订购的规格很大，可以考虑分装粉末保存，固体粉末是比较稳定的，-20℃ 可以保存三年。

问抑制剂产品应如何储存？

答粉末储存在 -20℃，可以存 3 年以上。母液一般储存于 -80℃，可以存 1 年以上，建议多分装几管，避免反复冻融。常用的存于 4℃，可放一周以上。

问购买多次产品，发现颜色不同，怎么办？

答首先请您确认批次，如果是同一个批次产品，请联系技术同事核查产品颜色。如果是不同批次，请您放心，颜色不同可能是生产工艺不同而造成的，生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑，可在官网下载相应的质检报告，我们是对产品质量负责的。

问如何设置母液浓度？

答母液浓度需低于官网给出的溶解度，在这个范围内，根据工作液浓度设置母液浓度，细胞实验中，建议母液浓度设定在工作液浓度的 1000 倍以上。
