The substrate was a DNA primer-template complex generated by annealing two oligomers: Template 5TTGTGGGTAGATAAATACAGACCTAAGTCCTTGAATGCCGCGTGCGTCCC and Primer 5-GGGACGC ACGCGGCATTCAAGGA. The assays had been performed at 250 nM polymerase, 7.5 nM DNA and 50 M of every single dNTP. The reaction buffer integrated 20 mM HEPES at pH 7.5, 100 mM NaCl, 0.2 mg/ml BSA, three mM MgCl2 and 0.5 mM TCEP. Time point samples had been taken until the reactions reached completion. Immediately after quenching the final sample, 90 minutes were allowed for fluorescence development just before data acquisition on a Perkin-Elmer Victor3 fluorescence plate reader employing a 535/30 nm excitation filter, 595/60 nm emission filter, and an averaging time of 1 sec.
