CD19 Antibody (B-1): sc-390244

CD19 Antibody (B-1) is a mouse monoclonal IgG2a kappa light chain antibody that detects CD19 of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). CD19 (B-1) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. CD19 is a crucial transmembrane glycoprotein that plays a significant role in B-cell development and function, as CD19 is selectively expressed on the surface of B-lymphocytes. CD19 contains two extracellular immunoglobulin-like domains, which are essential for interaction with other surface proteins and for initiating intracellular signaling pathways. Notably, CD19 forms functional complexes with proteins such as integrin β1, CD21, and CD81, which are vital for regulating B-cell activation, proliferation, and differentiation. Activation of CD19 leads to cross-linking of immunoglobulin chains and recruitment of Src family protein tyrosine kinases, thereby triggering downstream signaling cascades that are critical for B-cell responses. Continuous expression of CD19 throughout B-cell development and CD19′s role in terminal differentiation into plasma cells underscore CD19′s importance in the immune response, making anti-CD19 antibody (B-1) an invaluable tool for researchers studying B-cell biology and related disorders.
