|Cat.No. :||IL27-335H Optional Service: Optional requirements on this protein|
|Product Overview :||Recombinant Human IL27 Protein was produced by CHO Stable Cells expression system. This protein composed of IL27B subunit (NP_005746.2) (Met1-Lys229) and the N-terminally truncated IL27p28 (IL27A) subunit (NP_663634.2) (Phe29-Pro243) linked by an polypeptide linker was fused with a polyhistidine tag at the C-terminus. The purified protein was biotinylated in vitro.|
|Description :||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 p4-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.|
