Notes
Assay was done in Kinase buffer containing 20 uM Sphingosine and 20 uM ATP. Reaction was done at 30°C for 35 min. Amount of ATP transferred was calculated using Assay was done in Kinase buffer (40 mM Tris, pH 7.4, 20 mM MgCl2+, 0.1 mg/ml BSA) containing 20 uM Sphingosine and 20 uM ATP. Reaction was done at 30°C for 35 min. Amount of ATP transferred was calculated using Kinase-Glo reagent (Promega)
Avoid freeze/thaw cycles.
