S6 Flex M2

The S6 Flex M2 is a dedicated 4-color FluoroSpot reader, and so much more! It supports ELISPOT/FluoroSpot testing by enabling high-throughput PBMC viability counting, a rate limiting step for testing multiple PBMC samples in ELISPOT assays. The Flex is equipped with optics which, along with CTL’s dedicated LDA Cell Counting Suite permits live and dead cell counting in dozens of PBMC samples within minutes, including the documentation of the samples’ viability/fitness, and the calculation of resuspension volumes. The Flex is a multifunctional device that supports several assays which are standard in immune monitoring laboratories. Its live/dead cell counting ability, along with the TVA Cytotoxicity Suite, renders the Flex a high-throughput reader for cell-mediated cytotoxicity assays. Enabled by the BioSpot™ Software, this instrument permits automated reading of viral neutralization and infectivity assays in a wide range of well formats. The instrument comes with features supporting work in a regulated environment, and is high-throughput capable, handling up to 400 plates per run when equipped with our automated plate loader.
