The CsCl/EtBr gradient centrifugation method fractionates DNA and RNA molecules based on their density, where EtBr labels the nucleic acid bands. 3 Scientists have used this technique to extract large ...

The authors also tested whether the gradual DNA extraction method provided advantages over three previously described methods (predigestion, room-temperature phosphate treatment and bleach treatment) ...

Wallace and his team compared four common commercially available DNA extraction methods: DNeasy Plant (Qiagen), Quick DNA (Zymo), Extract-N-Amp (Sigma-Aldrich), and Power Soil Kit (Qiagen).

(A) Plasmid DNA concentrations and (B) A260/A280 and A260/A230 absorbance ratios were measured spectrometically. The average values ± standard deviations of n=23 replicate extractions are shown.

Scientists at the National Institute of Standards and Technology (NIST) have developed a new technology for measuring how ...

At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules.
