The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control hub, according to a study by researchers at Science Tokyo. Deleting a single ...

Deleting a single amino acid (Pro230) in the lower hinge produced half-IgG1 molecules with disrupted disulfide bonds and reoriented Fab and Fc regions, highlighting the hinge’s essential role in ...

Immunoglobulin gene analysis provides fundamental insight into B cell receptor structure and function. In B cell tumors, it can provide information on the cell of origin and predict clinical outcomes.

Antibodies play an important role in the immune system by binding to molecules called antigens at their respective epitopes. These interfaces or epitopes are structural entities determined by the ...

Antibodies—proteins that are produced by our immune system to protect us—are crucial for recognizing and getting rid of unwanted substances, or antigens, in our body. Although their role is universal, ...
