Description
Overview
Our Viability Probe has been specifically designed for use with Cyto-Mine® Chroma and optimized for use in multiplex assays. It enables our customers to perform high-throughput detection and selection of viable single cells in combination with other assays. For example detection of single-cell antibody secretion while simultaneously assessing cell viability, ensuring the selection of only viable, high-producing cells.
CO-ENCAPSULATION: Individual cells and fluorescent assay probes are encapsulated in picodroplets inside Cyto-Mine® Chroma.
SIMULTANEOUS DETECTION: The assay quantifies antibody secretion and assesses viability within the same picodroplet, distinguishing between high-producing, viable clones and apoptotic or dead cells.
EFFICIENT SELECTION: Non-viable cells are excluded from the workflow, ensuring that only healthy and productive clones progress to downstream development.
Who is it for?
- Cell Line Development (CLD) Teams – Select high-yielding, stable clones with confidence.
- CDMOs & BioPharma Companies – Accelerate therapeutic development.
- New and Existing Cyto-Mine® Chroma users – Expanding capabilities with next-level multiplex assays.
How it works
In this example, the fluorescent assay probes co-encapsulate with individual cells into picodroplets within Cyto-Mine® Chroma. Inside the picodroplets, these probes detect antibody secretion using Förster resonance energy transfer (FRET), while simultaneously detecting apoptotic markers by Annexin V staining. These fluorescent signals are used to sort and isolate high-producing, viable clones to help accelerate workflows including cell line development and antibody discovery.

Benefits
Reduce screening uncertainty by confirming secretion and viability at once. You get higher-quality hits and fewer false positives for follow up.
Improve downstream outcomes by ensuring only healthy, productive cells are selected. Minimize wasted time on non-viable clones and increase confidence in early-stage decisions.
Boost statistical power and rare hit recovery. Screen larger populations to uncover top performers faster, even in low-frequency events.
Unlock full platform performance. Run end-to-end assays without manual steps, freeing up your team for higher-priority tasks.
Spend less time troubleshooting, more time discovering. Validated reagents reduce setup complexity and give consistent results across users and sites.
