Our testing service analyzes plant samples for the presence of plant pathogens (viruses, bacteria, fungi and phytoplasma). BIOREBA has been offering this service since 1986 and recently has been accre-dited according to ISO/IEC 17025 (Swiss Testing Service No. 541).
We test plant material for customers in Switzerland and abroad with the same ELISA reagents and equipment as offered in this catalogue to our customers worldwide. In addition, other techniques and services such as PCR analysis are provided.

Our test service guarantees:
  • High quality standards (ISO/IEC 17025)
  • Reliable results
  • Confidentiality

Test methods

The serological method DAS-ELISA (double antibody sandwich enzyme-linked immunosorbant assay) is primarily used for the analysis of plant samples for the presence of specific pathogens. This method is economic and suitable in most cases. We also offer  the analysis of your samples with the molecular biological method polymerase chain reaction (classical or real-time PCR).


Antigen (pathogen) present in the sample is recognized by specific antibodies in microtiter plates. A color change indicates a positive result, whereas negative samples remain colorless.
Classical PCR.
Pathogen-specific DNA or RNA is amplified and then detected as fluorescent band with specific size in a gel.
Real-time PCR.
Pathogen-specific DNA or RNA is amplified and recorded real-time as fluorescent increase. This method allows to quantify the pathogen concentration in the sample.
