We describe the potential of microchip electrophoresis with a Hitachi SV1100, which can be used to evaluate the integrity of total RNA, for the analysis of synthesized RNA. There was little interference by DNA and/or the components of the in vitro transcription system with the microchip electrophoresis. The fluorescence intensity corresponding to the synthesized RNA increased in a time-dependent manner as to the RNA synthesis reaction on sequential analysis. A result can be obtained in 160 s and only 1/10 aliquots of samples, compared with the conventional method, are required. These results indicate the potential of microchip electrophoresis for sequential analysis of RNA synthesis.
