One important structure in these objects is a "sandwich" held together by cysteine bonds between two beta sheets. They are diversified through VDJ recombination and contain three key amino acid sequences called CDRs. These structures have Fv and Fc regions, and interconversion among the types of these produced by a cell is called (*) class switching. Only one type of these proteins can cross the placenta from mother to fetus, the G type, and the E type triggers mast cells' release of histamines. They are composed of two heavy and two light chains, and their variable regions participate in antigen binding. For 10 points, name these proteins also known as immunoglobulins.
