Notes
The reaction mixture contained 50 mM Tris-HCl, pH 7.5, 12.5 mM MgCl2, 1 mM -D-fructose-6- phosphate, 20 uM ATP, 2 mM DTT, 5 mM KH2PO4, and various amounts of PFKFB4 in a final volume of 50 uL. The reaction was incubated at 30°C for 30 min, the amount of ATP consumed was calculated using kinase-glo plus reagent (Promega).
Avoid freeze/thaw cycles. Storing diluted enzyme is not recommended. If necessary, use carrier protein (BSA 0.1 - 0.5%).
