Recombinant Human IGHG4 Protein

• Cat.No.: IGHG4-549H
• Product Overview: Recombinant human IgG4 Fc region (P01861) (Glu 99-Lys 327, 108Ser/Pro) was expressed and purified.

Specification

• Source: HEK293
• Species: Human
• Predicted N Terminal: Glu 99
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• Molecular Mass: The recombinant human IgG4-Fc consists of 229 amino acids and has a predicted molecular mass of 25.5 kDa. As a result of glycosylation, the apparent molecular mass of IgG4-Fc is approximately 35 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >95 % as determined by SDS-PAGE.
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
