说明;仅用于科研实验
PMSF is a inhibitor of serine proteases and acetylcholinesterase. It inhibits proteases such as
chymotrypsin, trypsin, thrombin and thiol proteases such as papain. PMSF inhibits serine proteases by
sulfonating serine residues at the active site.
Storage/Stability:
When stored as indicated, PMSF has a shelf-life of three years..
Preparation Instructions:
PMSF is soluble in anhydrous isopropanol at 35 mg/ml with heating, resulting in a clear to very slightly
hazy, colorless to faint yellow solution.
Recommended stock solution: 100 mM in anhydrous isopropanol or anhydrous (100%, not 95%) ethanol.
A 200 mM solution in dry solvent is stable for at least 9 months at 2-8° C.
PMSF is very unstable in the presence of water. The half-life of aqueous PMSF at 25° C at pH 7.0, 7.5,
and 8.0 is 110, 55, and 35 minute respectively.
Precautions and Disclaimer:
PMSF is considered a highly toxic cholinesterase inhibitor.

-20保存后溶液出现结晶正常么?2023-10-13 16:13:11
您好,是正常的,等到温度稍高一些混匀即可。
含有EDTA吗?2023-06-02 15:30:52
您好,不含EDTA。
与蛋白酶抑制剂有什么区别么,两者只需要加一个嘛?2023-03-12 20:35:06
您好,这个是丝氨酸蛋白酶抑制剂,如果需要别的蛋白酶抑制剂可以额外添加。
请问含EDTA吗?2022-12-07 10:41:34
您好,不含EDTA。
PMSF在水里面不稳定,裂解液是水溶液,PMSF加到裂解夜里还能起作用吗?2022-09-08 20:59:39
您好,PMSF因为其在水溶液中不稳定,所以用异丙醇或无水乙醇溶解,一般在用之前加入裂解液。
