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.

H2O
| ||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
