Interleukin-7 receptor subunit alpha (IL7Ra) also known as CD antigen CD127, which belongs to the type I cytokine receptor family and type 4 subfamily. IL7Ra /CD127 contains 1 fibronectin type-III domain. IL7Ra /CD127 is expressed on various cell types, including naive and memory T cells and many others. IL7Ra /CD127 is receptor for interleukin-7 and also acts as a receptor for thymic stromal lymphopoietin (TSLP). The IL7 receptor is a heterodimer of IL7R and IL2RG. The TSLP receptor is a heterodimer of CRLF2 and IL7R. This protein is fused with Fc fragment of human IgG1 at the C-terminus, has a calculated MW of 51 kDa. The predicted N-terminus is Glu 21. DTT-reduced Protein migrates as 66-90 kDa due to glycosylation. Purity ≥95%
