Simple mice test antibody complexity
Article Abstract:
A Univ of California-San Francisco team tested immune system complexity by developing a mouse with all antibody-producing genes knocked out and a gene for one specific antibody re-inserted. The mice produced the one prescribed antibody at first, but by adulthood were producing many varied antibodies.
