Crystallizable fragments composed of the carboxy-terminal halves of both IMMUNOGLOBULIN HEAVY CHAINS linked to each other by disulfide bonds. Fc fragments contain the carboxy-terminal parts of the heavy chain constant regions that are responsible for the effector functions of an immunoglobulin (COMPLEMENT fixation, binding to the cell membrane via FC RECEPTORS, and placental transport). IgG1 Fc was reported has a novel role as a potential anti-inflammatory drug for treatment of human autoimmune diseases.

Recombinant Human IgG Fc, Tag Free (FCC-H5214) is expressed from human 293 cells (HEK293). It contains AA Glu 99 - Lys 330 (Accession # P01857-1).
Predicted N-terminus: Glu 99

Molecular Characterization
This protein carries no "tag".
The protein has a calculated MW of 26.1 kDa. The protein migrates as 32-34 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Less than 1.0 EU per μg by the LAL method.

>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Please see Certificate of Analysis for specific instructions.
