Activation of Sphingosine kinase (Sphk) increases the bioactive lipid, sphingosine 1-phosphate (S1P) and has been observed in a variety of cancer cells. Phosphorylation of sphingosine by sphingosine kinase (Sphk) is the rate-limiting step in the cellular synthesis of S1P. A principle activation event is the phosphorylation of serine 225 of sphiongosine kinase 1. Inhibition of Sphk1 phosphorylation and hence, Sphk activity is an important target for the development of drugs for cancer, inflammation, cardioprotection as well as a many other indications.
Purification
Antigen Immunoaffiinity Purification
Immunogen
Rabbits were immunized with a synthetic peptide incorporating the serine 225 phosphorylation site of mouse sphingosie kinase 1
Antibody can be used for Western blotting (1-5 μg/mL). Antibody shows some cross reactivity (~10 % by ELISA) with other phosphoserine containing proteins. Optimal concentration should be evaluated by serial dilutions.
