1975 – _______ and ________ discovered how to fuse lymphocytes to produce a single cell line. This single cell line is immortal and able to produce specific antibodies.
1975 – Kohler and Milstein discovered how to fuse lymphocytes to produce a single cell line. This single cell line is immortal and able to produce specific antibodies.
1975- _________________ and __________________ discovered a technique to produce antibody arising from a single B cell, which has revolutionized serological testing. For their pioneering research, they were awarded the Nobel Prize in 1984.
