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.

IgG4 Protein, Human, Recombinant (S108P) is expressed in HEK293 mammalian cells. The predicted molecular weight is 25.5 kDa and the accession number is P01861.

A DNA sequence encoding the human IgG4 Fc region (P01861) (Glu 99-Lys 327, with mutation Ser 108 Pro) was expressed and purified. Predicted N terminal: Glu 99

≥ 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.
