Quantification and normalization


Whether you want to quantify just a few DNA or RNA samples, or need fully integrated quality control for your automated workflows, Tecan has the right solution to meet your needs.

Quantification and normalization of nucleic acids following nucleic acid extraction or as part of NGS workflows avoids poor quality results or downstream failures due to insufficient or contaminated samples, saving time and lowering costs.

Frida Reader

The Frida Reader module for Fluent workstations allows quantifying nucleic acids without sample loss. Designed to work in combination with the Air Flexible Channel Arm™ (AirFCA) of the Fluent Automation Workstation, this patented approach performs UV absorbance-based quantification and purity assessment in a hanging drop, avoiding the consumption of rare and precious samples following nucleic acid purification (NAP). It is ideal for precious or low volume samples, as the sample is aspirated back into the tip and can directly be used for further processing, such as normalization.

Infinite 200 PRO

DNA quantification can be achieved by measuring an aliquot with a fluorescent dye, such as PicoGreen® or QuantiFluor™, or by measuring the absorbance of the entire DNA sample.

DNA quantification and normalization workflows typically include the following steps:

  • Set-up of quantification assay
  • Determination of the DNA concentration in a reader
  • Calculation of a dilution scheme to achieve the target concentration for each well
  • Dilution of the DNA samples to the desired concentration

The Infinite 200 PRO can be integrated on the workdeck, on a side extension or below the workdeck, ensuring an optimal fit into your genomics workflow.

Straightforward integration of an Infinite reader on or below the workdeck of a Fluent platform.

Normalization workflow

The Freedom EVOware® Normalization Wizard is a software component that efficiently automates pipetting steps for the quantification and normalization of nucleic acid samples.

Samples of varying concentrations are diluted to a uniform concentration across the entire microplate. This enables Freedom EVO workstations to perform all the pipetting and microplate handling steps required for sample normalization tasks.

Fragment Analyzer INFINITY™
integrated nucleic acid quality control

Fragment analysis

Traditionally, quality analysis of DNA fragments is performed by agarose gel electrophoresis, which is both time consuming and labor intensive.

The Fragment Analyzer INFINITY (FAI) from Advanced Analytical offers automated multichannel capillary electrophoresis, providing high resolution separation of 96 samples in parallel.

It can accurately size and quantify nucleic acid fragments and smears from 50bp to 50kb, and can hold two different gel reagents for seamless switching between applications and sample types.

Over 20 reagent kits are available – each optimized for the analysis of different fragment lengths – for:

Integration of the FAI onto a Freedom EVO® liquid handling platform enables incorporation of important quality control checkpoints into automated genomics workflows.

This allows longer walkaway times and ensures that DNA fragments meet the quality control criteria necessary for subsequent sequencing or other downstream analyses.

Application Notes

Nucleic acid quantification and normalization is required in most genomics workflows, most commonly after the initial nucleic acid purification step, but consumes precious sample and can be tedious when performed manually. The versatility of the classical UV absorbance-based technique still makes it the ‘go to’ method for many applications, as it allows the concentration of all DNA and RNA types to be measured (based on the specific empirical extinction coefficient for each nucleic acid type) and provides simultaneous assessment of samples for impurities that could impair downstream applications.

The Frida Reader is an add-on module for the Fluent Automation Workstation that revolutionizes the way quantification and normalization are performed. It allows samples to be measured in a hanging drop at the end of a disposable pipette tip, completely eliminating sample loss for nucleic acid quantification.

DNA quantification and normalization are critical steps for a wide range of genomics applications, such as next generation sequencing and quantitative PCR. Due to the limitations of classical absorbance techniques, a number of more sensitive methods for quantification of double stranded DNA (dsDNA) have been developed over the years. Fluorescence-based techniques have proved popular with researchers, as the introduction of fluorescent dsDNA-binding dyes with minimal binding to single stranded DNA (ssDNA) and RNA allows selective quantification of even small amounts of dsDNA.

User Guides

The Frida Reader for Fluent offers UV-based concentration and purity measurements of nucleic acid samples in a hanging drop at the end of a disposable tip. This patented method is completely free of sample loss, as the hanging drop is aspirated back into the tip, and can be used for further processing (e.g. a normalization). No additional preparation steps, labware or reagents are required for the measurement, which offers precision and accuracy comparable to a reference reader over a range of 2 to 1,000 ng/μl.
