CD74 Antibody (A-6) is a mouse monoclonal IgG1 antibody that detects CD74 in mouse, rat, and 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). CD74, also known as the invariant chain, plays a crucial role in the immune system by regulating the loading of peptides onto major histocompatibility complex class II (MHC II) molecules, which are essential for presenting antigens to T lymphocytes. This process is vital for initiating adaptive immune responses, as CD74 allows the immune system to recognize and respond to pathogens effectively. CD74 is predominantly expressed in B lymphocytes and is also found in a subset of T lymphocytes, highlighting CD74′s importance in both humoral and cellular immunity. CD74 expression on these immune cells not only facilitates the proper functioning of MHC II but also serves as a marker for certain immune cell populations, making anti-CD74 antibody (A-6) an invaluable tool for researchers studying immune responses and related disorders.

I am using CD74 (A-6): sc-166047 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: Dr Ninau Qelp
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
