At the heart of RAPid 4’s sensor technology lies the sensor cassette. This contains two resonating sensors to provide high uniformity and sensitivity. To study an interaction, one of the interaction molecules is chemically immobilised to the sensor surface. Interactions are monitored by flowing the test sample over the coated sensor surface.

TTP LabTech offers a range of sensor cassettes where the crystal surface is processed to introduce a biologically inert chemical layer which allows specific targets to be coupled.

Fundamental to achieving high sample throughput is the ability to perform multiple cycles of an assay on the same sensor. TTP LabTech also offers reagent kits to optimise sensor surface regeneration by efficiently removing the bound material from the sensor surface whilst maintaining the activity of the immobilised molecule. Typically, more than 100 assay cycles can be performed using the same sensor surface.
