Antibody Structure Explained - Visual Guide to Immunoglobulin Architecture #11384 (License: Personal Use)

This image depicts a stylized 3D representation of an immunoglobulin G (IgG) antibody, rendered in vibrant purple with a textured surface to emphasize its molecular nature. The classic Y-shape illustrates the two identical antigen-binding fragments (Fab) at the tips and the crystallizable fragment (Fc) stem, which mediates immune cell activation. Such visualizations help convey how antibodies recognize and bind specific antigens with high specificity.

Used in educational, medical, or biotech web content to explain adaptive immunity, vaccine mechanisms, or monoclonal antibody therapeutics; targets students, researchers, clinicians, or informed lay audiences seeking foundational immunology knowledge.
