12368336463?profile=RESIZE_400xThe European Commission's Joint Research Centre (JRC) has published guidance on the selection and use of DNA extraction methods.

Extracting DNA of suitable quality and quantity from a test sample is a fundamental upstream step that underpins the confidence in a number of downstream analytical molecular biology based methods (e.g., qPCR. dPCR, NGS, etc.,).

This official guidance document provides advice on the selection and use of fit for purpose DNA extraction methods. Whilst this guidance uses the example of DNA extraction in the context of official controls for the analysis of genetically modified organisms (GMOs), the principles it describes are universally applicable to all DNA based methods including those for food authenticity.

Advice is provided on the selection of different protocols and decision support systems, and guidance provided on validation approaches and the assessment of DNA quality parameters, further illustrated with practical examples/solutions based on extensive collective experiences.

This guidance has also been added to the Quality section of this website.

12365337854?profile=RESIZE_584xThe Food Integrity Unit of the European Commission’s Joint Research Centre (JRC), is looking for laboratories with expertise in beeswax analyses, interested in participating in a method validation study by inter-laboratory comparison according to ISO 5725-2.                                                                
The goal is to evaluate repeatability and reproducibility of the gas chromatography based analytical method for quantifying paraffin n-alkanes respectively stearin/stearic acid in beeswax with the aim to identify potential adulteration of beeswax.                                                                                         
The participants will receive a set of beeswax test samples, the detailed analytical protocol of the method, and the necessary consumables, free of charge.                                                                   
If you interested in being part of this important project that will lead to the future standardisation of the method by an international standardisation organization, please contact:
