To evaluate the consistency of conventional RNA quality assessment techniques against automated microcapillary electrophoresis classifiers and determine their influence on downstream gene expression analyses.
Evaluated the reproducibility and consistency of traditional RNA quality indicators, including UV spectroscopy and 28S:18S ribosomal RNA peak area ratios.
Applied two automated, user-independent classifiers—the Degradometer and RNA Integrity Number (RIN) algorithms—to analyze microcapillary electrophoresis traces.
Assessed gene expression variability across RNA samples representing disparate integrity profiles using quantitative real-time PCR (Q-PCR).
Conventional metrics such as UV spectroscopy and 28S:18S area ratios produced inconsistent evaluations of RNA integrity.
The Degradometer and RIN systems yielded highly correlated quality metrics from microcapillary electrophoresis traces, with the RIN algorithm providing superior reliability.
Q-PCR showed a significant reduction in relative gene expression when comparing RNA samples of disparate quality, whereas samples of matched integrity yielded reliable comparisons.
