    PU.1 Antibody (G-11) is a mouse monoclonal IgA antibody that detects PU.1 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). PU.1 is a critical transcription factor belonging to the Ets family, playing a vital role in the regulation of gene expression during lymphoid development and immune response. PU.1 is primarily located in the nucleus of hematopoietic cells, where anti-PU.1 antibody (G-11) can detect specific DNA sequences bound to activate or repress target genes essential for B cell differentiation and function. PU.1′s nuclear localization orchestrates transcriptional programs necessary for the development of various immune cell types, including B cells and T cells, thereby influencing the overall immune system′s functionality. PU.1 interacts with other proteins such as Spi-B and Spi-C, which further modulate activity and contribute to the complex regulatory networks governing hematopoiesis. PU.1 (G-11) antibody serves as an invaluable tool for researchers studying immune cell development and function, providing insights into molecular mechanisms underlying immune responses and potential therapeutic targets for immune-related diseases.

    What application is the blocking peptide sc-390618 P appropriate for?

    Asked by: Germaine
    Thank you for your question. The blocking peptide is intended for use as a negative control, by pre-adsorbing the mouse monoclonal antibody against the antigen.
