Recombinant Human IL-7 R alpha / CD127 Protein, Mouse IgG2a Fc Tag, 100 µg

Background
Interleukin-7 receptor subunit alpha (IL7Ra) is 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.

Source
Recombinant Human IL-7 R alpha, Mouse IgG2a Fc Tag (IL7-H5258) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Gly 236 (Accession # P16871-1(I66T, V138I)).
Predicted N-terminus: Glu 21

Molecular Characterization
This protein carries a mouse IgG2a Fc tag at the C-terminus.
The protein has a calculated MW of 52.0 kDa. The protein migrates as 65-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>90% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Reconstitution
See Certificate of Analysis for reconstitution instructions and specific concentrations.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
