Method validation of in vitro RNA transcript analysis on the Agilent 2100 Bioanalyzer.

The Agilent 2100 Bioanalyzer can characterize in vitro RNA transcripts for their integrity, purity, concentration, and size. The results are comparable to denatured agarose electrophoresis with ethidium bromide staining and UV spectrophotometry combined. In this report, we describe our strategy for validating this method following the International Conference on Harmonization guidelines. The assay has a linear range of quantitation between 500 and 25 ng/microL. Quantitation accuracy is within +/-20% of measurements produced from spectrophotometry and sizing accuracy is within +/-7% based on theoretical sizes. Concentration and sizing measurements within a single assay produce RSDs that are <10 and <2%, respectively, indicating good precision. The method also maintains a tolerable precision when altering operator, day, and reagent kit lot. The RSD for quantitation is
