Data Examples
Detection of Human Phospho-BTK (Y551) by Western Blot. Western blot shows lysates of RL human non-Hodgkin's lymphoma B cell line and Ramos human Burkitt's lymphoma cell line untreated (-) or treated (+) with 0.1 mM Pervanadate (PV) for 10 minutes and 12 µg/mL Goat Anti-Human IgM μ Chain Antigen Affinity-purified Polyclonal Antibody (Catalog # G‑105‑C) for 2 minutes. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Phospho-BTK (Y551) Monoclonal Antibody (Catalog # MAB7659) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Phospho-BTK (Y551) at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Phospho-BTK (Y551) by Simple WesternTM. Simple Western lane view shows lysates of Ramos human Burkitt's lymphoma cell line untreated (-) or treated (+) with ultraviolet light (UV), loaded at 0.2 mg/mL. A specific band was detected for Phospho-BTK (Y551) at approximately 89 kDa (as indicated) using 20 µg/mL of Mouse Anti-Human Phospho-BTK (Y551) Monoclonal Antibody (Catalog # MAB7659). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: BTK
Bruton tyrosine kinase (Btk) is a 75 kDa cytoplasmic protein tyrosine kinase that is widely expressed in hematopoietic cells. Btk is required for B cell receptor signaling and B cell development. Defects in Btk result in X-linked agammaglobulinemia which is characterized by a severely decreased level of circulating antibodies. Like other Tec family kinases, Btk contains a Pleckstrin homology domain, a Tec homology domain, an SH3 domain, an SH2 domain, and a protein kinase domain. Association of the Btk SH2 domain with the B cell linker protein (BLNK) is required for the activation of PLCg by Btk. Btk can be activated by Lyn or Syk phosphorylation of Tyr551 within the catalytic domain. Within aa 546 - 556, human Btk shares 100% aa sequence identity with mouse and rat Btk.
