Description
Product Usage Information
Western Blotting: 1:1000
Immunoprecipitation: 1:50
Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody.
Protocol
Available protocols: Western Blotting, Immunoprecipitation
Specificity / Sensitivity
Phospho-Jak2 (Tyr1007/1008) Antibody detects endogenous levels of Jak2 only when phosphorylated at Tyr1007/1008. This antibody may cross-react with phospho-Jak1 and phospho-Tyk2.
Species Reactivity: Human, Mouse
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr1007/1008 of human Jak2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Members of the Janus family of tyrosine kinases (Jak1, Jak2, Jak3, and Tyk2) are activated by ligands binding to a number of associated cytokine receptors (1). Upon cytokine receptor activation, Jak proteins become autophosphorylated and phosphorylate their associated receptors to provide multiple binding sites for signaling proteins. These associated signaling proteins, such as Stats (2), Shc (3), insulin receptor substrates (4), and focal adhesion kinase (FAK) (5), typically contain SH2 or other phospho-tyrosine-binding domains. The tyrosine residues 1007/1008 of Jak2 in the putative activation loop are the homologous tyrosine residues 1054/1055 in Tyk2, which are important in the regulation of Tyk2 kinase activity (6).
