一般說明
与琼脂糖结合的蛋白A。
专为免疫沉淀应用而设计。本品用BSA封闭，减少非特异性结合，不能用于纯化；对小鼠IgG2a和IgG2b及兔IgG效果最好。
警告
毒性：标准处理（A）
外觀
在PBS中。
其他說明
琼脂糖溶液为即用型，可用于免疫沉淀。使用15µ l混悬剂/µg一抗。推荐将蛋白A-琼脂糖用于使用兔多克隆抗体或未修饰的小鼠IgG2a或IgG2b单克隆抗体的免疫沉淀测定。小鼠IgG1或IgG3和全部大鼠抗体与蛋白A的结合较弱。作为替代方案，使用蛋白G PLUS，蛋白G PLUS/蛋白A或兔第二步抗体将这些抗体与蛋白A桥接。预清除将使由非特异性沉淀产生额外的条带最小化。要进行预清除，将与免疫沉淀抗体相同物种的 20 µl 琼脂糖结合物和 1 µg 正常 IgG 加入样品中。当使用免疫印迹进行检测时，某些二抗可以与BSA或样品中存在的其他高浓度蛋白质发生非特异性反应。这可以通过降低二抗的浓度来消除。

Many enzymes are self-regulated and can either inhibit or enhance their own catalytic activity. Enzymes that do both are extremely rare. Many protein kinases autoactivate by autophosphorylating specific sites at their activation loop and are inactivated by phosphatases. Although mitogen-activated

Protein arginine methyltransferase 1 (PRMT1), PRMT4, and PRMT5 catalyze the methylation of arginine residues on target proteins. Previous work suggests that these enzymes regulate skeletal muscle plasticity. However, the function of PRMTs during disuse-induced muscle remodeling is unknown. The purpose
