Recombinant human IgG1 Fc region (AAC82527.1) (Glu 99-Lys 330) (one aa mutation,103 Cys/Ser) was expressed.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its ability to bind human CD16a-His in a functional ELISA.2. Measured by its ability to bind human CD16a-AVI-His in a functional ELISA.3.Measured by its ability to bind human CD16a-His in a functional ELISA.
The recombinant human IgG1 Fc consists of 232 amino acids and has a predicted molecular mass of 26 kDa. As a result of glycosylation, the apparent molecular mass of rhFc is approximately 32 kDa in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>95 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
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 4ºC before opening to recover the entire contents.
