The Agilent 2100 Bioanalyzer is a microfluidics-based platform which is replacing the labour-intensive formaldehyde gel electrophoresis. The bioanalyzer platform is available for the analysis of DNA, RNA, protein and cells. It only takes 1 hour for the entire assay with automated delivering high quality digital data output.  The ratio of RNA fragments (either 18S and 28S for eukaryotic RNA or 16S and 23S for prokaryotic RNA) is calculated and displayed as a RIN value for interpretation of sample quality. For fragmented DNA or DNA libraries analysis, DNA 7500 and High Sensitivity DNA analysis kits are available.
