产品详情
ATP-polyamine-biotin,是第一种可透过细胞的 ATP 类似物,是一种有效的激酶共底物。ATP-polyamine-biotin 可促进活细胞中激酶底物的生物素标记。
生物活性
ATP-polyamine-biotin, the first cell-permeable ATP analogue, is an efficient kinase cosubstrate. ATP-polyamine-biotin promotes biotin labeling of kinase substrates in live cells.
性状
Solid
体外研究(In Vitro)
ATP-polyamine-biotin (APB) is incubated with PKA kinase and full-length protein substrate, myelin basic protein (MBP). Biotinylation was observed only in presence of kinase. In addition, MBP biotinylation was lost in the absence of ATP-polyamine-biotin, in presence of the kinase inhibitor staursporine or upon incubation with acid due to cleavage of phosphoramidate bond. Biotinylated kemptide product is observed only in the presence of APB cosubstrate. has not independently confirmed the accuracy of these methods. They are for reference only.
