Product Description |
Recombinant Cynomolgus IL-18BP Protein is expressed from HEK293 with His tag at the C-Terminus; It contains Thr28-Pro207. |
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. |

|
Species |
Cynomolgus |
Biotinylated |
no |
Amino Acid Range |
Thr28-Pro207 |
Molecular Weight |
The protein has a predicted MW of 21.14 kDa. Due to glycosylation, the protein migrates to 35-65 kDa based on Bis-Tris PAGE result. |

Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
