|A DNA sequence encoding the mouse IL27 complex composed of EBI3 (O35228) (Met1-Pro228) and IL27A (Q8K3I6) (Phe29-Ser234) linked by an polypeptide linker was fused with the polyhistidine tag at the C-terminus.|
|In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.|
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|> 85 % as determined by SDS-PAGE|
|1. Measured by its binding ability in a functional ELISA. Immobilized mouse IL27-His at 10 μg/ml (100 μl/well) can bind human IL27RA-Fc (Cat:10489-H02H), The EC50 of human IL27RA-Fc (Cat:10489-H02H) is 0.26-0.62 μg/ml.|
2. Measured in antiviral assay using HepG2 cells infected with vesicular stomatitisvirus (VSV).
The ED50 for this effect is typically 0.07-0.42 μg/mL.
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant mouse IL27 comprises 442 amino acids and has a predicted molecular mass of 49.5 kDa. The apparent molecular mass of the protein is approximately 60 kDa in SDS-PAGE under reducing conditions due to glycosylation.|
|Lyophilized from sterile PBS, pH 7.4|
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
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 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), an IL-12 p40-related protein (IL-27B). IL-27 protein is an early product of activated antigen-presenting cells and drives 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.
