      Purified Mouse anti-Btk (pY551)/Itk (pY511)
      Purified Mouse anti-Btk (pY551)/Itk (pY511)
      Western blot analysis of Btk (pY551) in human Burkitt's lymphoma.  Cell lysates from control (Panel A) and pervanadate-treated (Panel B) Raji cells (ATCC CCL-86) were probed with Purified Mouse anti-Btk (pY551)/Itk (pY511) monoclonal antibody at concentrations of 0. 5, 0.25, and 0.125 µg/ml.  Btk (pY551) is identified as a band of about 77 kDa in the treated cell lysate.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
      4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

      24a/BTK (Y551)

      Bruton's tyrosine kinase (Btk) is a nonreceptor tyrosine kinase whose function is critical for proper B cell development and signaling.  The activity of Btk is regulated by Src mediated phosphorylation of the kinase domain at tyrosine 551 (Y551).  This event induces Btk kinase activity and subsequent autophosphorylation at Y223.  Phosphorylated Btk then associates with the cell membrane via the interaction of the PH domain with phosphatidylinositol 3, 4, 5-triphosphate.  

      The Tec family kinase Itk plays a critical role in signal transduction downstream of the T cell antigen receptor and has been implicated in the activation of phospholipase C-γ1 (PLCγ1), a key regulator of calcium mobilization and extracellular signal-regulated kinase (ERK) activation.  Itk is regulated by an activating transphosphorylation event in which Y511 in the kinase domain is phosphorylated by Lck.  

      The 24a/BTK (Y551) monoclonal antibody recognizes the Y551-phosphorylated form of human Btk and the Y511 phosphorylated form of human Itk.

      Purified
      Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
