Antibody Structure Diagram - Immune System Protein Visualization #3857126 (License: Personal Use)

This vector illustration depicts multiple immunoglobulin G (IgG)-type antibodies, each rendered as a classic Y-shaped molecule with two identical antigen-binding Fab regions (purple tips) and a stem-like Fc region (blue). The color contrast highlights functional domains, aiding conceptual understanding of antigen recognition and effector functions in adaptive immunity.

Used in biology textbooks, immunology lectures, healthcare websites, and scientific presentations to explain how antibodies bind pathogens; targets users seeking foundational or clinical knowledge about the immune system.
