Name :
Recombinant Human TCCR/IL-27R alpha Protein (hFc Tag), HPLC-verified
Biological Activity :
Background :
The interleukin-27 receptor is a type I cytokine receptor for interleukin-27. It is a heterodimer composed of the interleukin 27 receptor, alpha subunit, and glycoprotein 130. WSX-1/IL-27R, a class I cytokine receptor that is homologous to the β2 chain of the IL-12R in both sequence and structure, is highly expressed by resting/naive CD4+ T cells and CD8+ T cells. WSX-1/IL-27R belongs to the IL-6/IL-12 family of cytokines and induced proliferation of naive CD4(+) T cells and the generation of a Th1-type adaptive immune response. WSX-1/IL-27R functions as a receptor for IL27. IL-27 not only contributes to the development of an adaptive immune response through its action on CD4(+) T cells, it also directly acts on cells of the innate immune system. WSX-1/IL-27R requires IL6ST/gp130 to mediate signal transduction in response to IL27. This signaling system acts through STAT3 and STAT1. It is involved in the regulation of Th1-type immune responses. IL-27R also appears to be involved in innate defense mechanisms. IL27RA is essential for transcriptional activation of STAT1 and for augmenting the induction of T-bet expression during initiation of Th1 cell differentiation.

Molecular Weight :
The recombinant human IL27Rα/Fc is a disulfide-linked homodimeric protein after removal of the signal peptide. The reduced monomer consists of 722 amino acids and has a predicted molecular mass of 79 kDa. As a result of glycosylation, rh IL27Rα/Fc monomer migrates as an approximately 105-115 kDa band in SDS-PAGE under reducing conditions.

Storage and Stability :
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. 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.
Endotoxin Level :
< 1.0 EU per μg of the protein as determined by the LAL method
Protein Construction :
A DNA sequence encoding the extracellular domain (Met 1-Arg 514) of human IL27Rα (NP_004834.1) was fused with the Fc region of human IgG1 at the C-terminus.
