1.本蛋白酶抑制剂混合物为100×的储存液,使用时按照1:100的比例加入到裂解液中(例如,1ml裂解液中加入10μl蛋白酶抑制剂混合物),混匀后即可使用。根据需要,0.5M的EDTA也按照1:100的比例加入到裂解液中(如用于检测金属蛋白酶活性,则不宜添加EDTA)。含有蛋白酶抑制剂混合物的裂解液宜现用现配,不宜配制后冻存待后续使用。
2. 待所需的抑制剂添加完毕混匀后,就可以开始进行哺乳动物组织的裂解和蛋白提取。

IC50: 0.5 μM for both COX-1 and COX-2 in guinea pig whole blood(S)-Flurbiprofen is a dual inhibitor of COX-1 and COX-2.Non-steroidal anti-inflammatory drugs (NSAIDs) are potent inhibitors of both COX-1 and COX-2, but are frequently supplied as racemates. In the 2-aryl propionic acid NSAID family, cyclooxygenase inhibition resides primarily in the (S)-enantiomer.In vitro: It was found that the IC50 value of (S)-flurbiprofen was about 0.5 μM for both COX-1 and COX-2 in guinea pig whole blood [1].In vivo: The efficacy of multiple applications of S(+)-flurbiprofen plaster (SFPP) was evaluated for the alleviation of inflammatory pain and edema in rat adjuvant-induced arthritis model. Multiple applications of SFPP could exert a significant analgesic effect from the first day of application as compared to the other NSAID drugs. In terms of paw edema, SFPP could decrease edema from the second day after application. Moreover, multiple applications of SFPP were found to be superior to those of other NSAID drugs in terms of the analgesic effect [2].Clinical trial: Previous clinical study showed that 40 mg of S-flurbiprofen plaster showed remarkable pain relief in not only primary endpoint but also all the other endpoint with significant differences over placebo. The safety profile of S-flurbiprofen plaster 40 mg was not different from that of placebo. Thus, 40 mg was determined as the optimal tested dose [3].
注意事项:
抗逆滴加序列
每次向板内滴加抗原时,移液器滴头要与平面45度悬空,不要触碰到孔内的液体,由后向前依次滴加(即浓度由低往高滴加)。
抗感染反应期
抗原抗体在室温20~25℃下,必须反应30min以上,若环境温度低于室温,可将微量反应板置于恒温培养箱中,使二者充分反应。
旅游温度
磷酸盐缓冲液的pH值要在高压灭菌后进行滴定,往往在高压后pH值会有所改变,所以高压后再调一次pH值更为准确。磷酸盐缓冲液一经使用保存期不要超过3周。当pH<5.8时,红细胞会产生自凝现象;当pH>7.8时,图形洗脱加快,易造成肉眼观察产生误差;p H=7.2时,红细胞沉降最充分,图形最清晰。
当滴注 1%红细胞悬液时,应经常摇晃红细胞悬液,使红细胞均匀地分布在磷酸缓冲液中,以防止红细胞下降。
反应时间及温度
加入鸡红血球之后,反应板在室温(20~25℃)静置30~40min,对照孔血球下沉于孔底,即可判定结果。若室温达不到实验要求,需相应调整反应时间。当环境温度低于4℃时,红细胞发生自凝;高于37℃时,会发生反应物分离和红细胞溶血。

文献和实验S-腺苷甲硫氨酸 S- adenosylmethionine 亦称活性甲硫氨酸,在生物体内由 ATP与甲硫氨酸在甲硫氨酸活化酶的作用下合成。甲硫键是高能键,另外其丙基胺部分也加入到多胺化合物中。当胆碱、肌酸及其它甲基化合物生成时它作为甲基供体而起作用。认为甲硫氨酸的分解也经过此物质。
