Recombinant Human CD127 Protein

Product Name: Recombinant Human CD127 Protein
Catalog #:  hRP-1803
Manufacture:  LD Biopharma, Inc.

The protein encoded by human interleukin-7 receptor subunit alpha (IL7R, also named as CD127) gene is a receptor for interleukin 7 (IL7). The function of this receptor requires the interleukin 2 receptor, gamma chain (IL2RG), which is a common gamma chain shared by the receptors of various cytokines, including interleukins 2, 4, 7, 9, and 15. This protein has been shown to play a critical role in V(D)J recombination during lymphocyte development. Defects in this gene may be associated with severe combined immunodeficiency (SCID). Alternatively spliced transcript variants have been found.

Full-length extracellular domain of human CD127 cDNA (21 - 239aa, derived from BC067537) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its 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.
