Human IL-7 R alpha&TSLPR Protein
Recombinant Human IL-7 R alpha&TSLPR Protein is expressed from HEK293 with His tag at the C-terminus.It contains Glu21-Asp239 (IL-7 R alpha) and Gln23-Lys231 (TSLPR) [Accession | P16871-1(IL-7 R alpha)&Q9HC73-1(TSLPR)].
The protein has a predicted MW of 31.18 kDa (IL-7 R alpha) and 29.03 kDa (TSLPR). Due to glycosylation, the protein migrates to 58-68 kDa (IL-7 R alpha) and 50-58 kDa (TSLPR) based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Supplied as 0.22 μm filtered solution in PBS (pH 7.4).

Human IL-7 R alpha&TSLPR on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human IL-7 R alpha&TSLPR is greater than 95% as determined by SEC-HPLC.
Immobilized Human IL-7R alpha&TSLPR, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human TSLP, hFc Tag with the EC50 of 3.8ng/ml determined by ELISA (QC Test).
Human IL-7R alpha&TSLPR, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-7, No Tag with an affinity constant of 15.54 nM as determined in SPR assay (Biacore T200).
IL-7R alpha & TSLPR is an heterodimeric receptor, with TSLP as the ligand, which initiates downstream signaling pathways upon binding to TSLP and subsequently participates in thymus development and immune cell generation. Among them, IL-7R alpha is a component of both the IL-7 and TSLP receptors.
