Recombinant Human IL31 Protein

Product Name: Recombinant Human IL31 Protein
Catalog #:  HRP-1974
Manufacture:  LD Biopharma, Inc.

Human Interleukin-31 (IL31), which is made principally by activated Th2-type T cells, interacts with a heterodimeric receptor consisting of IL31RA and OSMR that is constitutively expressed on epithelial cells and keratinocytes. IL31 may be involved in the promotion of allergic skin disorders and in regulating other allergic diseases, such as asthma. It also enhances myeloid progenitor cell survival in vitro. IL31 also induces RETNLA and serum amyloid A protein expression in macrophage.

Full-length mature form of human IL31 cDNA (24 – 164 aa) was constructed with codon optimization gene synthesis and expressed with a human Alpha Fetal protein N-terminal-His-TEV cleavage site Tag (217aa) fusion at FAP N-terminal. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
