How Many Binding Sites Does IgG Antibody Have?

Discover the essential role of IgG antibodies with two binding sites for targeting pathogens effectively.

0 views

IgG antibodies have two antigen-binding sites, one on each arm of its Y-shaped structure. These sites are specific to the antigens they are designed to bind, allowing IgG to effectively neutralize pathogens or mark them for destruction by other immune cells.

FAQs & Answers

  1. What role do IgG antibodies play in the immune response? IgG antibodies help neutralize toxins and pathogens and can mark them for destruction by other immune cells.
  2. How is IgG structured? IgG has a Y-shaped structure with two arms, each containing a binding site specific to a particular antigen.
  3. Are there different types of IgG antibodies? Yes, there are four subclasses of IgG antibodies: IgG1, IgG2, IgG3, and IgG4, each with distinct roles in immune response.
  4. How do IgG antibodies bind to antigens? IgG antibodies recognize and bind to specific antigens through their unique binding sites based on the antigen's structure.
