Abstrakt: A method to determine the steady-state kinetic parameters of single-nucleotide insertion in replication was developed using an automated DNA sequencer. The insertion of nucleoside 5′-triphosphates into a 6-carboxyfluorescein-labeled primer by DNA polymerase was quantified from the band pattern on a gel using GeneScan software. The parameters determined by this method were consistent with those obtained by the conventional radioisotope-labeling method. This non-radioactive, fluorescent-based method is rapid and can handle a large number of samples to assess cognate or non-cognate base pair formation between natural or unnatural bases in replication.
