Automated Normalization using the JANUS Workstation

Many genomic samples have variable DNA contents and require dilution to a constant amount of nucleic acid in order to successfully perform downstream analyses such as multiplexed PCR-based genotyping. The JANUS® Automated Workstation offers a complete genomics solution that includes a normalization and dilution procedure following DNA quantification. DNA concentrations can be measured using a fluorescent DNA stain or determination of the absorbance ratio 260/280 nm, or a luminescence assay.

After quantification, the JANUS DNA Normalization Protocol uses output DNA concentration data to ‘intelligently’ dilute the DNA to a desired target amount per sample well, usually 1 ng. Once the normalization protocol is completed, samples are ready for further analysis.

The JANUS automated liquid handling workstation can enable:

  • Normalization and dilution using JANUS Normalization Protocol
  • Normalization using JANUS Victor Normalization Option with Workout data analysis software package
  • Normalization following fluorescent quantification using OliGreen® or PicoGreen® assay
  • Normalization following luminescent quantification using human specific Promega AluQuant assay

Get the benefits:

  • Fully automated genomic DNA quantification and normalization protocols provide diluted DNA suitable for reliable downstream multiplexed genotyping assays
  • High throughput processing increases throughput ~10 fold compared to manual processing
  • Disposable filter barrier tips minimize risk of cross contamination
  • Uses same JANUS workstation configuration as for PCR setup
  • A combined DNA Normalization & PCR Setup protocol carries out both DNA normalization/dilution and genotyping PCR setup
