title: A simple technique for studying immunoglobulin synthesis by normal and malignant plasma cells in vitro.
abstract: Plasma cells from human marrows are saturated with C-14 labelled amino acids, harvested and recultured in unlabelled growth medium. The appearance of radioactivity in the growth medium then provides a simple and rapid measure of protein synthesis. The secreted radio-labelled material is characterized by isoelectric focusing and autoradiography in acrylamide gels, a technique which has advantages over established serological methods.
