CSK Polyclonal Antibody Catalogue Numbers:BS74292-50, BS74292-100 Product: 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Swiss-Prot: P41240 Host: Rabbit Reactivity: Human, Mouse, Rat Applications: WB, IHC, IF/ICC All Applications: WB,1:500 - 1:2000 | IHC,1:50 - 1:200 | IF/ICC,1:50 - 1:200 Background: Non-receptor tyrosine-protein kinase that plays an important role in the regulation of cell growth, differentiation, migration and immune response. Phosphorylates tyrosine residues located in the C-terminal tails of Src-family kinases (SFKs including LCK, SRC, HCK, FYN, LYN, CSK or YES1. Upon tail phosphorylation, Src-family members engage in intramolecular interactions between the phosphotyrosine tail and the SH2 domain that result in an inactive conformation. To inhibit SFKs, CSK is recruited to the plasma membrane via binding to transmembrane proteins or adapter proteins located near the plasma membrane. Suppresses signaling by various surface receptors, including T-cell receptor (TCR and B-cell receptor (BCR by phosphorylating and maintaining inactive several positive effectors such as FYN or LCK. Purification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE). Storage and Stability: Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles. Bioworld Molecular Weight: 50KDa Specificity: Unmodification Note: For research use only, not for use in diagnostic procedure. Alternative Name: CSK Immunogen: Recombinant fusion protein of human CSK(NP_001120662.1). Conjugate: Unconjugated Modification: Unmodified
