Product Description |
Recombinant Human IL-18BP Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Thr31-Gly194. |
Product Background |
Cytokines were the first modern immunotherapies to produce durable responses in patients with advanced cancer,components of the interleukin-18 (IL-18) pathway are upregulated on tumour-infiltrating lymphocytes, suggesting that IL-18 therapy could enhance anti-tumour immunity. IL-18BP, a high-affinity IL-18 decoy receptor, is frequently upregulated in diverse human and mouse tumours and limits the anti-tumour activity of IL-18 in mice. |
