HLA-DQ Antibody (HLADQ1) is a mouse monoclonal IgG1 antibody that detects HLA-DQ in human samples through applications such as immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and flow cytometry (FCM). HLA-DQ is a crucial component of the major histocompatibility complex (MHC) class II molecules, which play a vital role in the immune response by presenting processed antigens to CD4+ T lymphocytes. The structure of HLA-DQ consists of two polypeptide chains, alpha and beta, that form a heterodimer capable of binding a diverse array of peptide antigens. This structural configuration facilitates the recognition of a wide variety of foreign peptides and ensures effective immune system responses to numerous pathogens. The ability of HLA-DQ to present antigens is essential for T cell activation, which orchestrates adaptive immune responses. Variations in HLA-DQ structure can influence susceptibility to autoimmune diseases, making anti-HLA-DQ antibody (HLADQ1) an invaluable tool for studying antigen presentation dynamics and HLA-DQ′s role in various immunological contexts.
