Assay Development

It is essential that COVID-19 tests are fast, accurate and scalable. Our immunoassay reagents improve stability and reliability in a wide range of assays.


PlateBlock™ is a blocking reagent specifically developed for serological assays (antigen-down assays). With PlateBlock™, false positives are reduced and researchers and patients can have confidence in the accuracy of the test results. Try PlateBlock™ and five reagents with our ELISA Sampler Package to create the optimal COVID-19 test including:


SafetyTector™ S brings essential user safety to rapid antigen tests. This extraction and dilution buffer inactivates COVID-19 in saliva specimens and nasopharyngeal swabs in immunoassays, preventing users from being infected by positive tests. The inactivation ability of SafetyTector™ S provides safety measures that have not been achieved by other virus-inactivating extraction buffers. 


Magnetic silica beads are also an excellent tool for assay development. Magnetic silica beads have applications in separation, concentration and purification of biomolecules, and are well suited as a solid phase in assay kits. With a variety of surface modifications, the user can choose the perfect beads for the application. Additionally, our magnetic silica beads are ideal for high-throughput and automated applications as they do not require columns or centrifugation steps. Learn more
