설명

애플리케이션

Diisopropylfluorophosphate has been used:

• in combination with inactivated thrombin in Affi-Gel 10 column for the purification of recombinant human thrombomodulin with its chondroitin sulfate chain (shrTMCSA)
• for inducing status epilepticus (SE) in adult rats
• as an irreversible serine protease inhibitor in human neutrophil subcellular fractions

생화학적/생리학적 작용

Potent inhibitor of serine proteases such as trypsin and chymotrypsin, and of acetylcholinesterase; also inhibits cathepsin G, cholinesterase, coagulation factor Xa, leucocyte elastase, pancreatic elastase, tissue kallikrein, plasmin, subtilisin, and thrombin. Inhibition of acetylcholinesterase makes this compound especially toxic. Inhibits apoptosis induced by ricin and bacterial toxins.

분석 메모

Typically used at a concentration of 0.10 mM. A safer alternative inhibitor for serine protease is phenylmethylsulfonyl fluoride (PMSF).

기타 정보

Stored properly at 2-8°C, in an unopened bottle, DIFP should be stable for a minimum of two years. DIFP
is unstable when exposed to moisture. DIFP will develop a dark yellow color upon decomposition.
