|---|---|---|---|
  Varying concentrations of enzyme were mixed with 1 µM substrate in cAB containing 100 µM ATP. Relative fluorescence units (RFU) decrease as a function of zyme activity.  Varying amounts of ATP were used in the absence or presence of enzyme. Percent activity was calculated based on the ΔRFU between samples.  Varying amounts of DESPH in 1% DMSO were added to enzyme (30 nM) and substrate (1 µM) in cAB containing 50 µM ATP.  Statistical data were produced using 0% (top) 100% phospho-calibrators (bottom) or 30 nM sphingosine kinase (middle). Z′-factors of 0.9 and 0.6 were obtained using phospho-calibrators or reacted samples, respectively. A Z′-factor of >0.5 indicates a robust assay. |
