1. Measured by its binding ability in a functional ELISA. Immobilized human IL27-His at 10 μg/ml (100 μl/well) can bind human IL27RA-Fc , The EC50 of human IL27RA-Fc is 0.2-0.46 μg/ml. 2. Measured in antiviral assays using HepG2 cells infected with vesicular stomatitisvirus(VSV). The ED50 for this effect is typically 23-92 ng/mL.

IL-27 Protein, Human, Recombinant (His) is expressed in CHO mammalian cells with His tag. The predicted molecular weight is 56 kDa and the accession number is NP_005746.2&NP_663634.2.

A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.

IL-27 protein is a member of the IL-6 superfamily, which is expressed on monocytes, endothelial cells, and dendritic cells. IL-27 protein is also referred to as the IL-12 p35-related protein, p28, is one subunit of a heterodimeric cytokine complex, and associates with another subunit EBI3 (EBV-induced gene 3), and IL-12 p40-related protein (IL-27B). IL-27 protein is an early product of activated antigen-presenting cells and drives the rapid clonal expansion of naive CD4(+) T cells and plays a role in the early regulation of Th1 cells initiation which drives efficient adaptive immune response. IL-27 protein has an antiproliferative activity on melanomas through WSX-1/STAT1 signaling. Thus, IL-27 protein may be an attractive candidate as an antitumor agent applicable to cancer immunotherapy.
