A recording fluorometric assay for dihydrofolate reductase is described. The technique measures the appearance of product, tetrahydrofolate, as the reaction proceeds. The assay can be accomplished with as little as 2 pmol of enzyme and is sufficiently sensitive to allow accurate kinetic studies using very low concentrations of substrate. Kinetic studies of both purified and crude preparations of enzyme are reported.
