The Genomics Core Facility aims to provide researchers with state-of-the-art high-throughput sequencing and microarray services. As part of our service packages, we provide guidelines to sample preparation and assistance with experimental design.
 
Quantification and quality control of DNA
 
Accurate measurement of DNA quantity and quality is crucial for a successful experiment. High-quality DNA should be high molecular weight and free of contaminants such as carbohydrates, proteins, and organic solvents.
 
  • We strongly recommend the use of fluorescent nucleic acid assay for the quantification of dsDNA using Quant-iT PicoGreen or Qubit assays.
  • To determine DNA integrity we recommend running a 1% agarose gel electrophoresis or Agilent TapeStation DNA tapescreens.
  • We encourage assessing purity by spectrophotometer (Nanodrop or equivalent). On the Nanodrop, DNA samples should have an A260/A280 ratio of 1.8 to 2.0, and an A260/A230 ratio higher than 2.0.
  • Samples should be delivered diluted in water or TE buffer.
  • For sample concentration please contact the core facility. Concentration will depend on the protocol.
 
Quantification and quality control of total RNA
 
Precise measurement of RNA quantity and quality is crucial for a successful experiment. RNA with no degradation and free of contaminants such as carbohydrates, proteins, and organic solvents is required.
 
  • Total RNA samples should be quantified using the Nanodrop spectrophotometer. RNA samples should have an A260/A280 ratio and A260/A230 of 1.8 to 2.0.
  • All RNA samples deliver for service will be subjected to quality control using the Agilent 2100 Bioanalyzer prior to downstream processing. The electropherogram and the RNA Integrity Number (RIN) of each sample will be used to assess the RNA integrity. If a sample has a lower RIN value than 8.0, the sample shows low quality and the user should be aware of the occurrence of possible bias in the analysis.
 
Additional costs related to poor sample quality will be the responsibility of the user.
 
The Genomics Core Facility recommends the use of Qiagen kits for RNA isolation. RNA should be DNase treated and dissolved in RNase free water.
