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.

科研君们,当埋头实验几月找到了目标基因片段,电泳时条带却突然消失了;千辛万苦分离纯化的物质,色谱图中却意外出现杂质峰,苦苦查询,可能仍找不到问题原因。若问题只在小小的吸头上,科研君的心还能淡定吗? 吸头的问题在哪里,如何保证纯净无污染的吸头?需要考虑以下几方面因素: 一、 吸头材质 吸头市场上,原材料基本都是聚丙烯塑料(低吸附,化学惰性高,使用温度范围广,无色透明)。也许大家不知道的是,同样是聚丙烯,品质会有大的差别。高品质的吸头一般采用天然 100% 纯聚丙烯,而低廉的吸头则很多
