Biosensor system optimises mammalian cell-based binding assay workflow

SAW Instruments, developer of the sam family of biosensors for real-time, label-free assays using living cells, is launching its new samX biosensor in North America.

The  samX provides several innovative features that further optimise the system for a mammalian cell-based binding assay workflow. These include an expansion in the number of sensor chips to two, increasing the channels available to 8. Each can be addressed by the fluidics individually or in combinations, a factor that also facilitates on-chip immobilisation at each sensor position. The system can be used with unfixed cells in suspension, which are injected afresh for each measurement, or adherent cells grown directly on the sensor chips themselves. Most importantly, assays are completed in mere minutes, enabling accurate real-time kinetics data to be captured.
