A full-size IgG antibody is a Y-shaped complex of two identical light chains, each with a variable and constant domain, and two heavy chains, each with one variable and three constant domains.

Antibodies are Y-shaped, having two sets of branches attached to a single stem. The arms of the Y are the so-called variable regions, the tips of the arms contain antigen-binding regions ...

Antibodies usually have a Y-shaped structure, and these hypervariable regions are located in the tips of the Y, where they detect and bind to foreign proteins, also known as antigens. The bottom ...

These chains are interconnected by disulfide bonds, resulting in a characteristic Y-shaped structure with a total molecular weight of approximately 150 kDa. Each antibody molecule possesses ...
