Although they can be naturally produced from a common germ cell, their isolation is difficult due to variations in possible epitope binding sites and epitope binding activities. Hybrids of human-mice versions can be constructed using recombinant DNA techniques and the mouse anti-human choriongonadotropin variety can be conjugated with a dye and employed in pregnancy tests. They can be produced artificially on a HAT medium through the fusion of an activated lymphocyte and cancerous bone marrow cell to form a hybridoma. For 10 points, what are these immunoglobulin molecules produced by plasma cells cloned from a single B cell that was activated by an antigen?
