II. Biological screening methodsSCIPPO M.-L., MAGHUIN-ROGISTER G.Abstract :
This article presents a synthesis of the various biological methods used to detect residues or contaminants in foods, by insisting on their evolution during these last 25 years and by illustrating with numerous examples. The biological methods are based on the
detection of a biological effect of the analyte of interest. In the years 60-70, this effect was detected by means of histology.
At present, the biological tests use cells in culture genetically modified to contain a reporter gene, activated when the analyte of interest is present in the culture medium. Get the PDF Contact person : G.Maghuin@ulg.ac.be |
