title: Repetitive hit-and-run fluoroimmunoassay for T-2 toxin.
abstract: A monoclonal antibody for T-2 toxin is converted to a Fab'-fluorescein derivative. The latter is specifically complexed onto a T-2 agarose gel. Fifteen successive doses of T-2 ranging from 1 to 50 ng are then repetitively and linearly detected using a column packed with a small volume (0.2 ml) of this gel without recharging with Fab'-fluorescein. For these assays the effluent from the column is monitored with a spectrofluorometer.
