Figure 1From: RNA quality in frozen breast cancer samples and the influence on gene expression analysis – a comparison of three evaluation methods using microcapillary electrophoresis tracesBioanalyzer electropherograms. Bioanalyzer electropherograms of three samples, a) Sample 3, b) Sample 5, and c) Sample 6 after different lengths of time: 50 seconds, 2–3 minutes, 10 minutes, and 30 minutes, respectively. Three methods were used for evaluating the RNA quality, see Methods. Pearson correlation coefficients were obtained, when the gene expression levels of the sample for the different time periods at room temperature were related to the gene expression levels of the sample left at room temperature for 50 seconds.Back to article page
