Kinetics of transcription in a minute column.

Immobilized enzymes or nucleic acids are widely used to analyze association and dissociation reactions. A pseudo-rapid kinetic method for studying transcription was developed by using an immobilized template DNA packed in a minute column, in a micro-scale liquid chromatography system. This method, which has a dead-time of only several seconds, is quick enough to allow analysis of the release of product RNA in transcription by Escherichia coli RNA polymerase. The method could be applied to most enzymes that interact with DNA.
