Human IgG4 Protein Product Information
Synonym:IgG4
Protein Construction:A DNA sequence encoding the human IgG4 Fc region (P01861) (Glu 99-Lys 327, 108Ser/Pro) was expressed and purified.
Species:Human
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human IgG4 Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Glu 99
Molecule 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.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Human IgG4 Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
