L-4-Oxalysine hydrochloride is a natural product isolated from the culture media of Streptomyces roseovirdofuscus in China which has shown antitumor activities.Alpha-fetoprotein (AFP) is expressed in BEL-7404 human hepatoma cells and L-4-Oxalysine suppresses AFP mRNA expression in the cells[1]. L-4-oxalysine functionally antagonizes the a-fetoprotein-induced suppression of the mitogen- and one-way mixed lymphocyte culture-induced proliferation of spleen lymphocytes and interleukin-6 production by these cells in mice bearing the hepatoma-22 tumor[2].Tbe ultrastructural efects of different doses of L-4-Oxalysine on hepatocytes in mice are most serious at day 1 after stopping treatment. Mice are given ig L-4-oxalysine (I-677) 10, 50, and 100 mg/kg for 7 d. On day 8 the hepatocytes show accumulation of lipid droplets followed by loss of matrices in cytoplasm. The total area of lipid droplets is far less than 25% of mean section of hepatocytes. The injury of mitochondria and RER is only found in the groups of medium and high dose[1]. L-4-oxalysine inhibits the proliferation of some mouse implanted tumors and pulmonary metastasis of mouse Lewis lung carcinoma[2].[1]. Dai ZQ, et al.

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。
