HEK293 cell lysate with overexpressed SPL-GFP (green fluorescent protein).
Storage: <-80°C. The enzyme is stable for 6 months from the date of receipt. Avoid repeat freeze thaw cycles.
Sphingsoine 1-phosphate lyase (SPL) (E.C.22.214.171.124) works as a key regulator of the final step of the sphingolipid degradative pathway by irreversibly breaking down the sphingosine-1-phosphate (S1P) to ethanolamine phosphate and hexadecenal. S1P signaling through its five receptors involves in many biological events such as proliferation, inflammation and apoptosis in cancer and other degenerative diseases.
A support protocol for detection of S1P lyase activity is available below.
