Description

BP4091: In Vivo Grade Recombinant Human IgG1 Fc protein (hIgG1 Fc)

The in vivo grade recombinant human IgG1 Fc protein (hIgG1 Fc, Glu 99 - Lys 330 of the constant region of the IgG1 heavy chain, Accession # P01857-1) was produced in mammalian cells and purified by protein A. The hIgG1 Fc protein includes the CH2 (111-223) and CH3 (224-330) domains of the heavy chain constant region as well as the hinge region (99-110) before the CH2 domain. The C103S version of the hIgG1 Fc protein is also available. The C103S substitution prevents improper cysteine bond formation in the absence of a light chain.
Molecular weight: Predicted 26.1 kDa. Due to glycosylation, the recombinant human IgG1 Fc protein migrates to 32-34 kDa based on the Bis-Tris PAGE result.
Purity: >95% by SDS-PAGE under reducing conditions
Endotoxin Level: Less than 1 EU/mg of protein as determined by LAL method.
Formulation: 0.2 μM filtered solution of 1x PBS.

Shipping: The in vivo grade recombinant human IgG1 Fc protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
1 month from date of receipt, 2 to 8°C as supplied.
3 months from date of receipt, -20°C to -70°C as supplied.

Background

The recombinant human IgG1 Fc protein (hIgG1 Fc) includes the CH2 and CH3 domains of the heavy chain constant region. Most of the therapeutic antibody drugs and Fc fusion proteins carry the natural human IgG1 Fc region or engineered mutants. The recombinant human IgG1 Fc protein can be used as the isotype control of the hIgG1 antibodies and the hIgG1 Fc fusion proteins in various in vitro and in vivo experiments.

Changes to the IgG Fc sequence including glycosylation sites have been used to modulate Fc functions. Even a single mutation may have both enhancement and abrogation effects of Fc binding. The following mutations have been introduced to alter the Fc region of an IgG1 antibody or an IgG1 Fc fusion protein to change its immunologic properties by Fc interaction with host proteins:
