Beta-Lapachone is found to inhibit the activity of topoisomerase I in a DNA unwinding assay. It inhibits the relaxation at 1μM. The potency of beta-Lapachone can be increased when pretreating topoisomerase I with beta-Lapachone for 5 min at 37°C. Beta-Lapachone is selective for topoisomerase I and shows no inhibition activity for topoisomerase II. Besides, beta-Lapachone is also proved to have no induction in topoisomerase I mediated DNA cleavage [1].Beta-Lapachone has anti-tumor efficacy in a broad spectrum of human carcinoma cells. It induces cell death of AD2780s, HT-29, DLD, G480 and MCF-7 with IC50 values of 2μM, 5μM, 5μM, 4μM and 2μM, respectively. It is found that beta-Lapachone induces cell death of both apoptosis and necrosis through releasing cytochrome C. Beta-Lapachone is also reported to affect cell cycle. It induces primarily S-phase arrest in SW480 cells, late S- and G2/M-phase arrest in SW620 cells and early S-phase arrest in DLD1 cells [2, 3].References:[1] Li CJ, Averboukh L, Pardee AB. beta-Lapachone, a novel DNA topoisomerase I inhibitor with a mode of action different from camptothecin.

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。
