Modern molecular biology offers an enormous range of possible applications. It relies on the detection of specific DNA or protein sequences.
DNA analysis is used in our laboratory in the areas of GMO analysis (detection and quantification), animal and plant detection, animal species identification and allergen detection at the DNA level. In addition, PCR offers a decisive time advantage over classical methods in the detection of pathogenic germs in food and the detection, differentiation and quantification of Legionella in water.
Proteins whose presence accounts for the allergenic potential of foods are best detected using the ELISA technique.
A methodology that is still relatively new and very innovative in routine applications is Next Generation Sequencing (NGS). It offers an enormous potential of possibilities in different areas, e.g. metabarcoding for the identification of all single components of a food or tracking of contaminations within farms or laboratories by whole genome sequencing (WGS).
