CellGlow™ Viability Assay for automated cell counting
DeNovix Inc. has launched CellGlow™, a new ready-to-use AO/PI Viability Assay for automated cell counting. Developed by DeNovix scientists in Wilmington, Delaware, CellGlow is designed to simplify and accelerate cell viability analysis for researchers who need rapid, reliable staining directly at the bench.
Ready-to-use AO/PI viability assay for streamlined workflows
The CellGlow AO/PI Viability Assay streamlines cell counting by replacing traditional liquid reagents with precision-coated, surface-stabilized fluorophores supplied in convenient strip tubes. This format removes the need for reagent preparation and reduces variability associated with manual staining steps.
Formulated for efficient room-temperature storage, CellGlow enables researchers to keep the assay on the bench next to their automated cell counter, supporting fast and consistent viability measurements in cell culture and cell biology workflows.
Simple three-step protocol with no incubation time
To use CellGlow, researchers:
- Aspirate 20 µL of their cell suspension.
- Pierce the seal of a well in the strip tube with a pipette tip.
- Briefly mix the sample.
The sample is immediately stained with fluorophores and is ready to load onto an automated cell counter, with no incubation time required. This rapid protocol is intended to support high-throughput and time-sensitive experiments.
Broad compatibility with automated cell counters
CellGlow can be used in conjunction with the DeNovix CellDrop™ Automated Cell Counter and is also compatible with a wide range of automated cell counters used in research laboratories. This flexibility allows laboratories to integrate CellGlow into existing imaging and counting platforms without changing their core instrumentation.
“We’re excited about the way CellGlow simplifies cell counting for researchers,” said Andrew Jones, lead in the development of CellGlow. “The ready-to-go format of this assay will benefit any researcher wanting a quick, easy way to stain their cells.”
