Antibody Structure Diagram: Light and Heavy Chains Explained #11367 (License: Personal Use)

This illustration depicts a classic Y-shaped immunoglobulin molecule, with two identical heavy chains forming the stem and part of the arms, and two light chains completing the antigen-binding tips. The heavy chains are shown in deep blue, while light chains are rendered in gradient pink-to-red for visual distinction, with labels pointing to each component. The structure emphasizes the modular domains critical for antigen recognition and immune signaling.

Used in immunology education, medical websites, and biotech resources to explain antibody architecture; matches user intent for learning basic immune system biology or preparing academic/clinical materials.
