Analytical performance of nucleic acid microvolume quantification using the Epoch Spectrophotometer System

24 Mar 2025

Nucleic acids such as DNA and RNA are derived from a variety of biological sources for potential use in downstream applications such as sequencing and gene expression analysis. This application note demonstrates the analytical performance of the Agilent BioTek Epoch spectrophotometer system and especially the Agilent BioTek Take3 multivolume plate with regard to linear dynamic range, limit of detection, precision, and accuracy using microvolume samples to verify its broad applicability to nucleic acid quantification. Comparative data were derived on an Epoch spectrophotometer system and a NanoDrop; performance was shown to be equivalent.

Agilent BioTek Epoch Microplate Spectrophotometer

Agilent Technologies

The Agilent BioTek Epoch microplate spectrophotometer has monochromator-based optics, for a filter-free, wide wavelength range for UV-Vis absorbance measurements. These measurements can be done in many microplate formats and in 2 µL samples when the available Take3 microvolume plate is used.

DNA / RNA QuantificationDetection and quantification of nucleic acids is important in molecular biology, cloning, expression, forensics and clinical diagnostics. Nucleic acids can be detected by labeling with colorimetric, fluorescent or radio labels and using in situ hybridization kits to identify specific sequences. Multiple nucleic acids can be detected and quantified at once using RNA / DNA detection beads or RNA / DNA microarrays.

Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.
