Nrf2, a transcription factor, is a basic leucine zipper (bZIP) protein that regulates the expression of antioxidant proteins that protect against oxidative damage triggered by injury and inflammation [4], such as NADPH, Glutathione, SRXN1, TXNRD1, HMOX1, GST, UGT and Mrps. Nrf2 plays an important role in the maintenance of homeostasis which can control the basal and inducible expression of a battery of genes with diverse physiological roles, including the preservation of redox balance, the metabolism and detoxification of xenobiotics, and the regulation of multiple metabolic pathways that ensure the provision of cellular energy[5].Bardoxolone methyl is a synthetic oleanane triterpenoid compound, which has no effect on the function and histology of normal kidneys but increased renal expression of Nrf2, HO-1 and NQO1 by western blotting analysis of mice kidneys and immunofluorescence staining, and can prevent AA-induced acute kidney injury and reduce AAI-induced TI injury in mRNA and protein levels through real-time PCR.[6] In conclusion, Bardoxolone methyl can prevent AAI-induced renal damage, and it may exert this renoprotective effects by activating the Nrf2 signaling pathway and inducing the downstream target genes expression. A phase 3 clinical trial evaluating bardoxolone methyl for the treatment of chronic kidney disease (CKD) was terminated in October 2012 after patients treated with the drug were found to have experienced a higher rate of heart-related adverse events, including heart failure, hospitalizations and deaths.[7] Now in 2014, Kyowa Hakko Kirin announced plans to evaluate both safety and efficacy of bardoxolone methyl in a Phase 2 clinical study to be performed in Japan for the treatment of CKD associated with type 2 diabetes.[8]References:1.Yates MS, Tauchi M, Katsuoka F, et al."Pharmacodynamic characterization of chemopreventive triterpenoids as exceptionally potent inducers of Nrf2-regulated genes."

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。
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。
