Scientific Data

Western Blot Detection of Mouse/Rat Jak2 antibody by Western Blot. View Larger

Detection of Mouse/Rat Jak2 by Western Blot. Western blot shows lysates of DA3 mouse myeloma cell line, PT18 mouse mast/basophil cell line, and L6 rat myoblast cell lines. PVDF membrane was probed with 1 µg/mL of Mouse/Rat Jak2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2988) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Jak2 at approximately 125 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Jak2

Janus Kinase 2 (Jak2) belongs to a family of protein tyrosine kinases that couple to cytokine receptors and are activated by ligand binding to these receptors. Activation of Jak2 and other family members Jak1, Jak3, and Tyk2 occurs via phosphorylation at two adjacent tyrosine residues as well as potentially one or more serine residues. Jaks activate members of the STAT family of transcription factors by phosphorylating critical tyrosine regulatory sites. Jak2 plays an essential role in interferon gamma signaling.
