Sentence examples for microarray to calculate from inspiring English sources

In this study we have adapted a statistical method that utilizes absolute signal intensities from a reference set of positive controls and negative non-homologous control sequences to determine the absolute intensity range in each channel that may be used with a certain confidence level on a particular microarray to calculate expression ratios.
