Product nameATP-gamma-S, Kinase substrate
- ATP gamma S
Substrate and inhibitor of ATP-dependent enzyme systems. Hydrolyzed very slowly by phosphatases and most ATPases. Once thiophosphorylated, proteins are resistant to protein phosphatases. P2 purinergic receptor agonist.
Kinase reaction reagent to be used with ab92570 rabbit monoclonal to thiophosphate ester for the identification of direct kinase substrates as mentioned in Allen JJ et al. Nat Methods 4:511-6 (2007).
After the kinase of interest has accepted ATP-γ-S, p-Nitrobenzyl mesylate (ab138910) can be used to alkylate the thiophospholyation site on the substrates. A thiophosphate ester rabbit monoclonal antibody (ab92570) is introduced to identify the tagged substrates.
It is suggested to add 100 ng of ATP-γ-S to a 30 µL kinase buffer. See Allen JJ et al. Nat Methods 4:511-6 (2007); Supp. Material.
Chemical nameAdenosine 5'-(3-thiotriphosphate) tetralithium salt
