SEE ALSO...

Btk Antibody (DFS) is a mouse monoclonal IgG2a antibody that detects Bruton′s tyrosine kinase (Btk) in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), and flow cytometry (FCM). Btk plays a crucial role in B cell development and signaling, making Btk essential for the immune response. Mutations in the Btk gene can lead to X-linked agammaglobulinemia, a condition characterized by a significant reduction in B cells and immunoglobulins, which leaves individuals susceptible to infections. Btk is primarily located in the cytoplasm and becomes activated upon B cell receptor engagement, leading to downstream signaling that promotes cell survival and proliferation. Understanding the function and regulation of Btk is vital for developing targeted therapies for immunodeficiencies and certain types of cancers, as Btk dysregulation can contribute to malignancies. Anti-Btk antibody (DFS) serves as an invaluable tool for researchers studying B cell biology and related pathologies, providing reliable detection and characterization of Btk.

Can Btk (DFS): sc-81735 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: jenniferc
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, Btk (DFS): sc-81735 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
