The S6 Flex™ M2 is a dedicated 4-color FluoroSpot reader — and much more! Designed for high-throughput ELISPOT/FluoroSpot testing, it streamlines PBMC viability counting, a common rate-limiting step in processing multiple samples for ELISPOT assays.

Equipped with advanced optics and powered by CTL’s LDA Cell Counting Suite, the Flex can perform rapid live/dead cell counting on dozens of PBMC samples within minutes. It also documents sample viability/fitness and calculates accurate resuspension volumes.

The Flex is a versatile instrument that supports various assays standard in immune monitoring laboratories. Its combination of live/dead cell counting and the TVA Cytotoxicity Suite makes it a high-throughput solution for cell-mediated cytotoxicity assays.

With BioSpot™ Software integration, the S6 Flex™ M2 delivers automated readings for viral neutralization and infectivity assays across multiple well formats. Designed to meet the demands of regulated environments, it supports high-throughput operations, handling up to 400 plates per run with our automated plate loader.
