ATP-polyamine-biotin - CAS 1800401-93-7

ATP-polyamine-biotin is a cell-permeable, efficient kinase cosubstrate with conversions and kinetics similar to those of other known ATP analogues. APB shows a cytotoxicity EC50 value of 19 ± 1 mM. ATP-polyamine-biotin is shown to promote biotin labeling of kinase substrates in live cells and has future applications in phosphoprotein purification and analysis. APB is cell-permeable and nontoxic at low mM concentrations, with cell penetration and labeling dependent on the polyamine linker.
