Fig. 3From: High-throughput iSpinach fluorescent aptamer-based real-time monitoring of in vitro transcriptionEffects of ribonucleotide triphosphate and MgCl2 concentrations on the STAR system. A Effect of NTP concentrations ranging from 0.5Â mM to 6Â mM. The relative fluorescent units were measured every 5Â min. Error bars are standard errors of the mean (SEM). B Effect of MgCl2 concentrations ranging from 5 to 80Â mM. The relative fluorescent units were measured every 6Â min. The inset shows the results of denaturing PAGE analysis of the 60-min transcription products under different MgCl2 concentrations. Error bars represent the standard deviation of the triplicate experimentsBack to article page
