Chemical characterisation of the Fab and Fc fragments from surface immunoglobulin

Nature, 1980
Immunoglobulin (Ig) molecules of the M and D classes are present on the membranes of B lymphocytes (sIg), where they serve as antigen receptors1–6. sIg is a biosynthetically stable membrane protein which requires either denaturing conditions or detergents to free it from other membrane constituents1,7–9.

Investigation of the cooperative structure of Fc fragments from myeloma immunoglobulin G.

Biochemistry, 1998
The cooperative structure of Fc fragments prepared from myeloma human IgG1 was studied using scanning microcalorimetry and fluorescence at pH 4.2-8.0. It was shown that the first to be melted are CH2 domains whose interaction with each other is rather weak, while that with CH3 domains is strong.

Structural comparison of fucosylated and nonfucosylated Fc fragments of human immunoglobulin G1.

Journal of Molecular Biology, 2007
Removal of the fucose residue from the oligosaccharides attached to Asn297 of human immunoglobulin G1 (IgG1) results in a significant enhancement of antibody-dependent cellular cytotoxicity (ADCC) via improved IgG1 binding to Fcgamma receptor IIIa. To provide structural insight into the mechanisms of affinity enhancement, we determined the crystal ...

FC-like fragments in peptic digests of human immunoglobulin G.

The Journal of Immunology, 1968
When the products of digestion of human immunoglobulin G with pepsin are compared to those obtained with papain, one major difference appears to involve the recovery of the Fc fragment.

Conjugates of Superoxide Dismutase with the Fc Fragment of Immunoglobulin G

The Journal of Biochemistry, 1991
We constructed conjugates of superoxide dismutase (SOD) and the Fc fragment of human immunoglobulin G. The lysyl residues of bovine erythrocyte Cu,Zn-SOD were covalently linked with cysteine residues of the Fc fragment using N-succinimidyl 4-(N-maleimido)-butylate as a crosslinking agent.
