|Product Overview :
||Recombinant fragment, corresponding to amino acids 781-1124 of Human JAK3 with N-terminal proprietary tag expressed in a Baculovirus infected Sf9 cell expression system; 344 amino acids, 64kDa.
||The protein encoded by this gene is a member of the Janus kinase (JAK) family of tyrosine kinases involved in cytokine receptor-mediated intracellular signal transduction. It is predominantly expressed in immune cells and transduces a signal in response to its activation via tyrosine phosphorylation by interleukin receptors. Mutations in this gene are associated with autosomal SCID (severe combined immunodeficiency disease).
|Tissue specificity :
||In NK cells and an NK-like cell line but not in resting T-cells or in other tissues. The S-form is more commonly seen in hematopoietic lines, whereas the B-form is detected in cells both of hematopoietic and epithelial origins.
|Biological activity :
||The Specific activity of JAK3-27631TH was determined to be 91 nmol/min/mg.
|Storage buffer :
||Preservative: NoneConstituents: 25% Glycerol, 50mM Tris HCl, 150mM Sodium chloride, 0.25mM DTT, 0.1mM EGTA, 0.1mM EDTA, 0.1mM PMSF, pH 7.5
