使用方法：
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。

Beta-Sitosterol (purity>80%) includes β-sitosterol (≥80%), stigmasterol, campesterol and brassicasterol mainly. Beta-Sitosterol is a plant sterol. Beta-Sitosterol (purity>98%) interfere with multiple cell signaling pathways, including cell cycle, apoptosis, proliferation, survival, invasion, angiogenesis, metastasis and inflammation[1].Bioactivity-guided isolation afforded three compounds from the hexane fraction of E. indica, namely, Beta-Sitosterol (β-sitosterol), Stigmasterol, and Lutein. Both compounds are found to possess very low PPL inhibition activity, that is, 2.99±0.80% (Beta-Sitosterol) of inhibition at 100 μg/mL (242 μM) and 2.68±0.38% (Stigmasterol) of inhibition at 100 μg/mL (243 μM), respectively. Weak PPL inhibition activity of Beta-Sitosterol and Stigmasterol isolated from Alpinia zerumbet with IC50 value of 99.99±1.86 μg/mL and 125.05±4.76 μg/mL, respectively, in comparison with the inhibition shown by Curcumin (IC50=4.92±0.21 μg/mL) and Quercetin (IC50=18.60±0.86 μg/mL) which are used as positive controls in their study. Beta-Sitosterol and Stigmasterol are recorded with weak PPL inhibitory activity of only 3.0±0.8% and 2.7±0.4% at 100 μg/mL, respectively, (i.e., 242 μM and 243 μM) in contrast (34.5±5.4% at 100 μg/mL), which are comparatively lower than that recorded in literature (i.e., 50% PPL inhibition at 100 μg/mL)[1]. Sitosterol is an important compound extracted from the leaves of Aloe vera. It inhibits the growth of promastigotes of L. donovani, a causative agent for life threatening visceral leishmaniasis disease[2].Beta-Sitosterol (β-sitosterol) treatment significantly reduced the immobility time at three doses (10, 20, and 30 mg/kg) in the Forced Swim Test (FST) and Tail Suspension Test (TST), indicating an antidepressant effect. This effect is similar to the positive control fluoxetine (20 mg/kg) at a dose of 30 mg/kg, where the strongest effect is orved compared with the control group (P < 0.001). The same effects are orved for three doses of Beta-Sitosterol in the TST. The % DID values are as follows: FST: 39.27% (10 mg/kg), 51.23% (20 mg/kg), and 57.48% (30 mg/kg); TST: 31.63% (10 mg/kg), 43.95% (20 mg/kg), and 53.38% (30 mg/kg). These results indicate that Beta-Sitosterol has a significant antidepressant activity in mice during the FST and TST. Furthermore, Beta-Sitosterol exhibits the antidepressant effect in a dose-dependent manner[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。

文献和实验相关实验
C29 H50 O。又称豆甾 -5-烯 -3β -醇， 24R-乙基胆甾 -5烯 -3β -醇。是以谷类（希文， sitos）命名的甾醇（ sterol）。后来已知是α -，β -以及γ -谷甾醇等的混合物。现在知道α体是 C30 甾酵，γ体是 C2 及 C29 的甾醇混合物，因为它们已不被称为谷甾醇，所以仅留下β -谷甾醇具有谷甾醇的名称。它是植物界中分布最广的甾醇，可为毛地黄皂苷（ digitonin）沉淀。
多聚-β-羟丁酸poly-β-hydroxybutyricacid
几种芽孢杆菌属（Bacillus），假单胞菌属（Pseudomonas）、螺菌属（Spirillum）、固氮菌属（Azotobacter）以及其他许多种细菌在菌体内制造的贮藏物质。 在光学显微镜下可以因折光或呈颗粒状而被观察到，并可用苏丹黑染色。在细菌中作为代替油脂贮藏物，而合成此化合物。一般在培养基中氮源缺乏而碳源多的条件下合成，如果供给氮化合物，水解成单体的β-羟丁酸后，经过乙酰乙酸、乙酰CoA，被利用来合成生物体内各种成分
