Key Features

>> Accurate – From label-free cell monitoring to fluorescence-based assays, the Omni adds dynamic visual results to any experiment.

>> Fast – Minimize user-to-user variability with advanced image analysis that incorporates innovative machine-learning algorithms.

>> Powerful  – Get better data with software that assesses the count, size and circularity of colonies in a sample.


The clonogenic assay (or colony formation assay) is an in vitro cell survival assay that evaluates the ability of single cells to survive treatment and reproduce to form colonies. Using the Omni devices, you can monitor colony growth over days or weeks, not limiting data acquisition to a singular time point.

Metrics provided by the Clonogenic Assay Module:

  • >> Count - number of colonies formed
  • >> Size (µm2) - average area/size of colonies
  • >> Circularity - average colony circularity
