|ICC/IF||Use a concentration of 5 µg/ml.|
FunctionCatalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra-and extracellular functions. Also acts on D-erythro-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol.
Tissue specificityWidely expressed with highest levels in adult liver, kidney, heart and skeletal muscle.
Sequence similaritiesContains 1 DAGKc domain.

ICC/IF image of ab37980 stained HepG2 cells. The cells were 4% Formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab37980, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 Goat anti-Rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Predicted band size: 42 kDa
Observed band size: 47 kDa why is the actual band size different from the predicted?
Additional bands at: 200 kDa. We are unsure as to the identity of these extra bands.
