Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.

IL-4R & IL2RG Heterodimer Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 52.74 kDa and the accession number is NP_000409.1.

Human

HEK293 Cells

A DNA sequence encoding the human IL4R (NP_000409.1)(Met1-His232) was expressed, constructed the plasmid 1; A DNA sequence encoding the human IL2RG (P31785-1) (Met1-Asn254) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the IL4R & IL2RG heterodimer was purified. Predicted N terminal: Met 26 & Leu 23

≥ 95 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.

A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
