Products
Image-based analyzers for ELISPOT/FluoroSpot and colony/plaque assays
Laboratory analyzers combining automated image capture with analysis software for enumeration and morphometric measurement of spots, colonies and plaques across plate formats.
Modular image-analysis software suites
Modular software frameworks for object recognition, standardized counting, HDR imaging, statistical analysis and workflow integration for ELISPOT/FluoroSpot and colony/plaque assays.
ELISPOT and FluoroSpot assay kits and components
Enzymatic and fluorescent assay kits for T and B cell detection across species and analytes (single-color to multi-color kits), plus assay buffers and positive controls.
Serum-free media portfolio for PBMC
Media formulations designed for washing, freezing/thawing and testing PBMC with low background and high antigen-specific signal.
Characterized cryopreserved PBMC (ePBMC)
Cryopreserved PBMC panels characterized for HLA loci, predefined antigen-specific responses and donor metadata, available as controls and reference samples.
Cell counting and stimulation consumables
Consumables including live/dead cell counting kits, hemocytometer packs and polyclonal B cell stimulators for sample QC and assay preparation.
