Unit Definition:
A unit of sphingosine kinase activity is defined as the amount of enzyme required to produce 1 pmol of S1P per minute at 37°C.




Assay Conditions:
Sphingosine kinase activity was determined using D-erythro-sphingosine and ATP as substrates. Assay condition: 50 mM HEPES, pH 7.4, 150 mM NaCl, 5 mM MgCl
