bioautography

(1) A bioassay based upon the ability of some compounds (e.g., vitamin B12) to enhance the growth of some organisms or compounds and to repress the growth of others, which is used to assay certain antibiotics.
(2) The use of cells to detect their attachment or other reaction in the presence of a particular substance (e.g.), adhesion proteins on an electrophoretic gel
