Western blot shows lysates of Rat‑2 rat embryonic fibroblast cell line, Y3‑Ag rat myeloid cell line, and L6 rat myoblast cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse/Rat Jak1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF602) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Jak1 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Jak1 was detected in immersion fixed mouse splenocytes using Goat Anti-Mouse/Rat Jak1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF602) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Janus Kinase 1 (Jak1) belongs to a family of protein tyrosine kinases that couple to cytokine receptors and are activated by ligand binding to these receptors. Activation of Jak1 occurs via phosphorylation at two adjacent tyrosine residues, Y1022 and Y1023, within the kinase domain. Jaks activate members of the STAT family of transcription factors by phosphorylating critical tyrosine regulatory sites. Jak1 is required for the activation of STAT1 and STAT2 in response to interferon alpha.
