    • IHC image of CSB-RA227790A0HU diluted at 1:100 and staining in paraffin-embedded human colon cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

產品詳情

  • 產品描述：

    JAK1 is one of the Janus family kinases (JAKs) that are involved in cell growth, survival, development, and differentiation of a variety of cells but are critically important for immune cells and hematopoietic cells. Genetic studies revealed that JAK1 is negatively regulated by SHP2. The level of phosphorylated JAK1 is increased in SHP2--/fibroblasts after IFN-γ stimulation. JAK1 is also necessary for the induction of IRF1 mRNA, thus establishing a requirement for the JAK/STAT pathway in the IL-6 response. JAK1 is crucial for NK cell maturation. Somatic JAK1 mutations have been related to gynecologic cancers.

    The recombinant JAK1 antibody was prepared by obtaining the antibody genes, cloning the genes into a plasma vector to construct vector clone, transfecting the vector clone into a mammalian cell line for transient expression, and purifying the antibody by Affinity-chromatography. This recombinant JAK1 antibody has been verified to detect the JAK1 protein from Human in the ELISA, IHC.

  • 功能：
    Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway. Kinase partner for the interleukin (IL)-2 receptor as well as interleukin (IL)-10 receptor. Directly phosphorylates STAT but also activates STAT signaling through the transactivation of other JAK kinases associated with signaling receptors.
