Fluorometric assay for DNA polymerases and reverse transcriptase.
We report a quick, easy and inexpensive fluorometric assay that measures the activity of replication enzymes using Pico-GreenTM. The systems tested include replication of the natural template M13 Gori by E. coli DNA polymerase III holoenzyme and the replication of a synthetic homopolymer by human immunodeficiency virus reverse transcriptase. A direct comparison of the fluorometric assay with the conventional isotopic assay shows that the fluorometric assay accurately reflects the extent of replication. By performing the assay reactions directly in 96-well plates and using a fluorescence plate reader to determine the extent of reaction, the time required to measure replication activities is significantly shortened.
