Scientific Data Images for Human/Mouse/Rat Jak1 Antibody

Detection of Jak1 antibody in Jurkat Human Cell Line antibody by Flow Cytometry.

Detection of Jak1 in Jurkat Human Cell Line by Flow Cytometry.

Jurkat human acute T cell leukemia cell line was stained with Rat Anti-Human/Mouse/Rat Jak1 Monoclonal Antibody (Catalog # MAB4260, filled histogram) or isotype control antibody (MAB0061, open histogram), followed by Phycoerythrin-conjugated Anti-Rat IgG F(ab')2Secondary Antibody (F0105B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.
Detection of Human and Mouse Jak1 antibody by Western Blot.

Detection of Human and Mouse Jak1 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, K562 human chronic myelogenous leukemia cell line, A20 mouse B cell lymphoma cell line, and L1.2 mouse pro-B cell line. PVDF membrane was probed with 1 µg/mL of Rat Anti-Human/Mouse/Rat Jak1 Monoclonal Antibody (Catalog # MAB4260) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). 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 3.
Jak1 antibody in Human Epidermis by Immunohistochemistry (IHC-P).

Jak1 in Human Epidermis.

Jak1 was detected in immersion fixed paraffin-embedded sections of human epidermis using 25 µg/mL Rat Anti-Human/Mouse/Rat Jak1 Monoclonal Antibody (Catalog # MAB4260) overnight at 4 °C. Tissue was stained with the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; CTS017) and counterstained with hematoxylin (blue).

Background: Jak1

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.
