{"product_id":"cd137l-polyclonal-antibody-20ul","title":"CD137L Polyclonal Antibody, 20ul","description":"\u003cp\u003eThe protein (tumor necrosis factor superfamily member 9) encoded by TNFSF9 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. The ligand encoded by this gene, TNFSF9\/4-1BBL, has been shown to reactivate anergic T lymphocytes in addition to promoting T lymphocyte proliferation. This cytokine has also been shown to be 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":"BT LAB","offers":[{"title":"Default Title","offer_id":56507939422581,"sku":"BT-AP01353-20ul","price":97.2,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/Antibody_main_1.jpg?v=1766393459","url":"https:\/\/www.labcart.com\/products\/cd137l-polyclonal-antibody-20ul","provider":"LabCart Life Science","version":"1.0","type":"link"}
