UniProt
P08571
Synonym(s):
SphK2, sphingosine kinase 2, SPK2
Specific Activity:
20 U/µg
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 MgCl2, 1 mM DTT, 3 µM Na orthovanadate, 0.5 mM ATP, 4 µM D-erythrosphingosine, and 0.75 μg/ml sphingosine kinase 2 at 37°C for 30 min. ATP reduction is detected using Kinase-Glo® Luminescent Kinase Assay Platform (Promega Corporation, Madison, WI).
Formulation:
25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol, and 3 mM DTT.
Format:
Aqueous buffer solution
Storage / Stability:
>6 months at –80°C.
Application(s):
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
