This peptide is used to specifically block Jak2 (D2E12) Rabbit mAb #3230 reactivity.
The quality of the peptide was evaluated by reversed-phase HPLC and by mass spectrometry. The peptide blocks Jak2 (D2E12) Rabbit mAb #3230 by dot blot.
Use as a blocking reagent to evaluate the specificity of antibody reactivity in dot blot protocols.
For Western immunoblotting, add 10 µl of antibody and 10 µl of blocking peptide to 10 ml of antibody dilution buffer, and incubate at room
temperature for 30 minutes before allowing to react with the blot.
Supplied in 20 mM potassium phosphate (pH 7.0), 50 mM NaCl, 0.1 mM EDTA, 1 mg/ml BSA and 5% glycerol. 1% DMSO. Store at –20°C.
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.
