Bulk Cytotoxicity Workflows

Automate cell-mediated cytotoxicity assays with a minimum amount of sample

Easily create dose-response curves analyzing multiple Effector : Target ratios identified by the AI-powered software within each channel

Generate an entire dose-response curve per microfluidic channel, up to 16 dose-response curves per CC-Array plate, using only a few thousand effector cells per channel. Bulk cytotoxicity workflows available for suspension target cells.

Multiparametric Workflows

Unravel the heterogeneity of your cell therapy samples

Define potency of each cell subset in your cell therapy batches

Single-cell multiparametric analysis of cytotoxicity and phenotype enables unprecedented depth of analysis:

  • Rapidly define frequency of killer and serial killer cells
  • Measure potency of cell subsets, e.g. CD4 and CD8, in a single assay using just one microfluidic channel per sample
  • Generate a unified potency score, highly reproducible across runs

Combined with parallel screening of multiple conditions in a single run, multiparametric analysis enables comprehensive testing of cell therapy candidates from numerous process options, against multiple target cells, to rapidly identify the most suitable candidates.

Serial Killing Assay

Find your supercharged cells

Quantify frequency of serial killer cells in just 5% of the time taken for conventional bulk assays​

A single immune cell can be evaluated for immunophenotype and ability to kill two or more target cells within a time lapsed study. Leveraging this protocol, the CC-Array technology allows quantification of serial killing at a single-cell resolution in just 24 hours instead of weeks needed by conventional bulk assays. The manual tedious work required in re-challenge assays is replaced with a fully automated process requiring just 20 minutes hand-on time.

Unified Potency Score

Comparability through a Unified Potency Score

Streamline your discovery or process development workflows by ensuring comparability among different product variants or process options

A Unified Potency Score (UPS) is calculated from single-cell cytotoxicity data providing a single indicator for the potency of your cells.

Frequency of both killer and serial killer cells contribute to the UPS, for a comprehensive evaluation of the potency of your product.

Once an incubation time and target cell line are defined, the UPS (time, target) is a standardized score allowing direct comparison of multiple products or product candidates, irrespective of the source of your cells, the batch or cell therapy type.
