Acyl-RAC(阿西尔-树脂辅助捕获)是一种高度敏感、可靠且易于执行的方法,用于检测各种生物样品中半胱氨酸残留物(S-acycyy)的可逆脂改性。

丙烯酸辅助捕获或Acyl-RAC是一种敏感可靠的方法,可用于检测各种生物样品中的蛋白质S-环化。该协议绕过代谢标签和放射性标签的一些限制,并允许同时检测多种蛋白质的S-细胞化。不仅活细胞,而且原组织和冷冻样品。

S-二聚变可以调节各种细胞过程,如蛋白质贩运、血浆膜靶向、信号转导、铁传输和蛋白质-蛋白质相互作用。对于每个实验,使用新鲜准备好的羟基胺溶液,并经过仔细调整的pH值,以确保硫酯键的高效和特定的裂解非常重要。通过演示这种方法,它对于氯仿、甲醇沉淀等步骤至关重要。
