otubules. Mc-VC-PAB-MMAE is a thiol reactive derivative of MMAE that contains a cathepsin B cleavable valine-citrulline p-aminobenzylcarbamate linkage (VC-PAB). Mc-VC-PAB-MMAE is used to prepare antibody-drug conjugates, such as brentuximab vedotin (Seattle Genetics).nnThis product is a control ADC for any IgG type antibody labeled with MMAE, particularly any ADC made using CellMosaic's Antibody MMAE Conjugation Kit (Cat#: CM11409). The product uses a human IgG1 subtype antibody that does not bind to the target. It has an average of 4 MMAE loaded on each antibody and can be used for accessing the effect of MMAE alone (non-specific toxicity). The product uses a very low endotoxin level antibody as a starting material (≤0.5 EU/mg by the LAL method). The preparation and purification are conducted under pyrogen free environment. The final product is assayed for endotoxin to make sure it is suitable for cell culture and animal studies. The loading is confirmed by various methods including UV, HPLC, and difference MALDI-TOF MS.nnThe final conjugate is lyophilized from phosphate buffered saline containing sugar-based stabilizer for easy shipping and storage. nnThe product is sold as 1 vial of 100 microgram (Cat# CM51100-100UG), 1 vial of 500 micrograms (Cat# CM51100-500UG), or 2 vials of 500 micrograms (Cat# CM51100-1MG).

产品描述
“MMAE(单甲基澳瑞他汀E)是一种抗有丝分裂剂,与微管蛋白结合,抑制微管的组装。 Mc-VC-PAB-MMAE是MMAE的硫醇反应性衍生物,含有组织蛋白酶B可裂解的缬氨酸-瓜氨酸对氨基苄基氨基甲酸酯键(VC-PA B)。 Mc-VC-PAB-MMAE用于制备抗体-药物偶联物,如维布妥昔单抗(西雅图遗传学公司)。nn该产品是用MMAE标记的任何IgG型抗体的对照ADC,特别是使用CellMosaic的抗体MMAE缀合试剂盒(目录号:CM 11409)制备的任何ADC。 该产品使用不与靶标结合的人IgG 1亚型抗体。 其在每个抗体上平均负载4个MMAE,可用于评估单独MMAE的作用(非特异性毒性)。 本品使用极低内毒素水平的抗体作为起始物料(LAL法测定≤0.5 EU/mg)。 在无热原环境下进行制备和纯化。 对最终产品进行内毒素测定,以确保其适用于细胞培养和动物研究。 通过各种方法(包括UV、HPLC和差分MALDI-TOF MS)确认上样量。nn最终结合物由含有糖基稳定剂的磷酸盐缓冲盐水冻干,以便于运输和储存。 nnThe final conjugate is lyophilized from phosphate buffered saline containing sugar-based stabilizer for easy shipping and storage. nnThe product is sold as 1 vial of 100 microgram (Cat# CM51100-100UG), 1 vial of 500 micrograms (Cat# CM51100-500UG), or 2 vials of 500 micrograms (Cat# CM51100-1MG).
