The Core provides nucleic acid assessment services to quantify and determine purity and size of RNA and DNA isolated from nearly any biological source. The quality assessment (QA) service is supported with a variety of measurement instruments, including several UV spectrophotometers, a plate reader, a fluorimeter and state-of-the-art Bioanalyzer systems including the Agilent 2100 and TapeStation 4200.

Proper quantitation and size analysis of RNA and DNA samples prior to downstream processing provides useful insight into sample quality, purity, and integrity which can help ensure high quality data and improved reproducibility.

Our trained staff is experienced at analyzing both RNA and DNA quality and the core provides comprehensive assessment reports to aid investigators with interpreting their results.
