These proteins are all comprised of two light and two heavy chains.
These proteins are cleaved by papain to release one Fc fragment and two Fab fragments. The many possible paratopes of these proteins are produced by near-random assembly of variable, diverse, and joining segments during somatic recombination. One isotype of these proteins can pass through placenta and is symbolized IgG. These proteins are all comprised of two light and two heavy chains. For 10 points, name these y-shaped proteins, which are produced in the specific immune response in the presence of antigens.
