MHC class II Antibody (12F4) is a mouse monoclonal IgG1 antibody that detects MHC class II in human samples through immunofluorescence (IF) applications. MHC class II molecules play a crucial role in the immune response by presenting processed exogenous antigens to helper T lymphocytes, which are essential for orchestrating adaptive immunity. These molecules are primarily located on the surface of professional antigen-presenting cells, such as dendritic cells, macrophages, and B cells, where they facilitate the activation of CD4+ T cells. MHC class II (12F4) antibody recognizes longer antigenic peptides, typically ranging from 13 to 18 amino acids, which is vital for effective immune recognition and response. This structural characteristic allows for a diverse range of peptide binding, which is essential for the immune system′s ability to recognize and respond to a wide variety of pathogens. The interaction between MHC class II and T cell receptors is a key event in the activation of the adaptive immune response, making anti-MHC class II antibody (12F4) an invaluable tool for studying immune function and the mechanisms of immune-mediated diseases.

Does 12F4 (#sc53896) target HLA-DR, DB, DQ? Or is it a pan MHC-II antibody? Additionally, do you sell them at 25mg or 50mg samples and if you do, would they be more concentrated? We are looking for MHC-II antibodies for immunoprecipitation.
