-Constant Region (Portion)
-2 Heavy Chain
-2 Light Chain
-Hinge(flexibility)
-Disulfide Bonds
Antigen Binding Region - Correct Answer - a region on an antibody that binds to antigens
-binds the epitope
-Composed of one constant and one variable domain of each of the heavy and the light chain

*J (joining)
-encodes both the antigen binding region and the constant region
Hinge - Correct Answer allows for antibodies to be flexible
-that is relatively unstructured domain, which allows it great freedom of motion
Disulfide Bonds - Correct Answer -holds together the two halves of the antibody
-formed between two cysteine residues
What are the five isotypes of antibodies? How are they different from one
another? - Correct Answer IgA (alpha)
IgD (delta)
IgE (epsilon)
IgG (gamma)
IgM (mu)
They are classed according to the heavy chain
