TNFRSF4, commonly known as OX40 or CD134, serves as a critical costimulatory receptor within the tumor necrosis factor receptor superfamily. Expressed primarily on activated T cells, this receptor plays a pivotal role in sustaining T cell responses, promoting survival, and enhancing cytokine production. Its involvement in both autoimmune regulation and anti-tumor immunity has positioned TNFRSF4 as a compelling target for immunotherapy research and studies exploring T cell-mediated immune responses.
This recombinant monoclonal antibody, clone 7F4, offers researchers the consistency and reliability that comes with sequence-defined production. Unlike traditional hybridoma-derived antibodies, recombinant technology ensures lot-to-lot reproducibility, allowing you to maintain experimental continuity across long-term studies without concerns about performance drift between batches.
The antibody has been validated for immunohistochemistry applications, with successful staining demonstrated in paraffin-embedded human tonsil tissue. Using a citrate buffer antigen retrieval method at pH 6.0 and working dilutions between 1:50 and 1:200, the antibody produces clear visualization of TNFRSF4-positive cells when detected with HRP-conjugated secondary antibodies and DAB chromogen. The tonsil represents an ideal validation tissue given its rich lymphoid architecture and abundance of activated immune cell populations where OX40 expression would be expected.
Supplied in a liquid format with glycerol-based buffer for stability, this unconjugated antibody provides flexibility for researchers to optimize their detection systems. Whether investigating T cell activation dynamics, exploring checkpoint biology, or characterizing immune infiltrates in tissue samples, this antibody supports immunology and stem cell research applications where understanding costimulatory receptor expression is essential to experimental goals.
