MHC class II Antibody (15G4) is a mouse monoclonal IgG1 antibody that detects MHC class II in mouse samples through applications such as immunoprecipitation (IP), immunofluorescence (IF), and flow cytometry (FCM). 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. MHC class II proteins are primarily located on the surface of antigen-presenting cells, including B cells, dendritic cells, and macrophages, where MHC class II facilitates the activation of CD4+ T cells. The ability of MHC class II to bind longer antigenic peptides, typically ranging from 13 to 18 amino acids, is vital for effective immune signaling, as such binding allows for a diverse range of antigens to be presented, thus enhancing the immune system′s ability to recognize and respond to various pathogens. The interaction between MHC class II and T cell receptors is a key event in the immune response, making MHC class II (15G4) antibody essential for understanding immune regulation and potential therapeutic interventions. MHC class II (15G4) antibody serves as an invaluable tool for researchers investigating the complexities of immune responses in mouse models.

Can MHC class II (15G4): sc-53946 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: jerojero
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, MHC class II (15G4): sc-53946 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.

Rated 4 out of 5 by from Works ok on western blotWorks on ok western blot. I cut the membrane so I do not know how non specific they are, so I am giving 4 stars which is still a very high rating.
