    Ox40 Antibody (6A371) is a rat monoclonal IgG1 antibody that detects Ox40 in mouse samples through applications such as immunofluorescence (IF) and flow cytometry (FCM). Ox40, also known as CD134 or Ox40R, plays a crucial role in the immune response by regulating the activation and differentiation of CD4+ T lymphocytes. Anti-Ox40 antibody (6A371) recognizes a protein primarily located on the surface of activated CD4+ T cells, where Ox40 interacts with Ox40L, predominantly expressed on activated B cells. The engagement of Ox40 with Ox40L provides a vital costimulatory signal that enhances T cell activation, promoting effective immune responses. This interaction is particularly important for the generation of robust T helper cell responses, which are essential for orchestrating adaptive immunity and ensuring the body can effectively combat infections and maintain tissue homeostasis. Ox40 (6A371) antibody serves as an invaluable tool for researchers studying T cell dynamics and the underlying mechanisms of immune regulation, making Ox40 (6A371) monoclonal antibody a key asset in the exploration of autoimmune diseases, inflammation, and therapeutic interventions.
