PU.1 Antibody (A-7) is a mouse monoclonal IgG1 antibody that detects PU.1 in human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), 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 PU.1 binds to specific DNA sequences to activate genes essential for B cell differentiation and function. Nuclear localization of PU.1 enables interaction with other transcription factors and co-regulators, orchestrating a complex network of gene expression that influences the development of various immune cell types, including B cells and T cells. PU.1 transactivates multiple genes involved in B cell signaling, such as CD72, CD20, and Bruton′s tyrosine kinase (Btk), which are essential for B cell maturation and function. Precise regulation of PU.1 expression and activity maintains immune homeostasis, and dysregulation can lead to hematological malignancies. As a key regulator in immune cell development, anti-PU.1 antibody (A-7) serves as an invaluable tool for researchers studying immune responses and related disorders.

I'm looking for a PU.1 stain that will stain frozen mouse brain tissue - could you help? Preferably cross-reactive with Human.

Asked by: Nogs
Thanks for you question. Anti-PU.1 Antibody (C-3):sc-390405 is recommended for detection of PU.1 of mouse and human origin by IF, and IHC(P).

I am using PU.1 (A-7): sc-365208 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: cjMara
We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
