Antibody Structure Icon - Free Vector Graphic for Immunology & Biotech #3857143 (License: Personal Use)

This vector-style illustration depicts the canonical Y-shaped structure of an immunoglobulin G (IgG) antibody, featuring two identical antigen-binding Fab regions at the tips and a constant Fc region forming the stem. The clean black outline on a transparent background makes it suitable for digital use across scientific presentations, websites, and educational materials. The simplified design emphasizes functional domains without molecular detail.

Commonly used in biomedical websites, textbooks, research posters, and health-tech dashboards to symbolize immunity, diagnostics, or therapeutic antibodies. Matches user intent for quick visual reference, iconography, or open-access scientific illustration.
