Santa Cruz Biotechnology offers a broad range of HLA-DR4 monoclonal antibodies for research in immunology and related fields. HLA-DR4 monoclonal antibodies are validated for multiple applications, including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). HLA-DR4 is a major histocompatibility complex (MHC) class II molecule that plays a crucial role in the immune response by presenting peptides to CD4+ T cells. Understanding HLA-DR4 function has revealed important insights into autoimmune diseases, such as rheumatoid arthritis and type 1 diabetes. Studying HLA-DR4 continues to advance knowledge of disease mechanisms and therapeutic development. Researchers worldwide rely on precise detection methods to explore HLA-DR4's role in immune system regulation and disease progression. Current investigations focus on how HLA-DR4 influences antigen presentation and T cell responses in both healthy and pathological conditions. Santa Cruz Biotechnology monoclonal antibodies for HLA-DR4 enable researchers to conduct detailed studies that expand scientific understanding of immune system function and disease mechanisms.
