{"product_id":"nsj-v8184btn-500ul","title":"CD137L Antibody \/ 4-1BBL \/ TNFSF9, 500 ul","description":"\u003cp\u003eTNFSF9 \/ 4-1BBL is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This transmembrane cytokine is a bidirectional signal transducer that acts as a ligand for TNFRSF9 \/ 4-1BB, which is a costimulatory receptor molecule in T lymphocytes. This cytokine and its receptor are involved in the antigen presentation process and in the generation of cytotoxic T cells. The receptor TNFRSF9 \/ 4-1BB is absent from resting T lymphocytes but rapidly expressed upon antigenic stimulation. It has been shown to reactivate anergic T lymphocytes in addition to promoting T lymphocyte proliferation. This cytokine is required for the optimal CD8 responses in CD8 T cells. This cytokine is expressed in carcinoma cell lines, and is thought to be involved in T cell-tumor cell interaction.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"500 ul","offer_id":51548057796888,"sku":"V8184BTN","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_c4107423-753a-4551-aa7e-44137a6add44.jpg?v=1768272632","url":"https:\/\/danabiosci.com\/products\/nsj-v8184btn-500ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
