Antibody Structure, Function and Genetics
“What a memorable day! The Pneumococcal reactants were most exciting—sugarplums were dancing in my head.”
- —Michael Potter, “The Early History of Plasma Cell Tumors in Mice, 1954–1976.”
Matching Immunoglobulins to their Antigens

In their Building 8 laboratory, Potter and Elizabeth Mushinski began screening the immunoglobulins produced by plasma cell tumors against all types of antigens to match antibody to antigen. In 1968, they identified the MOPC315 immunoglobulin and its antigen, pneumococcal C polysaccharide, which is a component of the bacteria that causes pneumonia. Michael P.
