The immune system’s capacity to distinguish self from non-self is in large part mediated by immunoglobulins, with IgG playing a pivotal role in both protective and pathological responses.

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 ...

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 ...

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, ...

Immunoglobulins are central to shaping immune responses and are critical tools for probing biological mechanisms in biomedical research. However, selecting an inappropriate antibody isotype can lead ...
