Two platforms have been established on which new tests are being developed continuously, both are based on sequence specific hybridisation following amplification by PCR. For single mutation assays, a microplate-based detection system is applied, whereas for multi-mutation assays, teststrips are  used as „macro-arrays“. All tests include ready-to use reagents for sample prep, amplification and mutation detection. Reliable multiplex amplification protocols provide convenience and allow testing of samples with very limited volumes. Using the straightforward StripAssay format, testing for twenty and more mutations may be completed in less than five hours without costly equipment. Instrumentation is available for automated processing of StripAssays External proposals for assay development are welcome and will be carefully evaluated for their feasibility and market potential. In 2001, ViennaLab and Hoffmann-La Roche signed an Agreement granting ViennaLab worldwide, non-exclusive rights to manufacture and sell PCR-based diagnostic tests.
