Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Jak1 (6G4) Rabbit mAb detects endogenous levels of total Jak1 protein. It does not cross react with other Jak family members.

Source / Purification

Rabbit monoclonal antibodies are prepared from rabbit spleens immunized with a synthetic peptide (KLH-coupled) corresponding to residues surrounding Cys775 of Jak1.

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.
