Gene Editing
Gene Editing is Hard, but Finding the Edited Cells Doesn’t Have to Be
Gene editing holds tremendous promise for advancing medical research, but isolating viable, edited monoclonal colonies can be a roadblock. For researchers facing challenges growing cells post-editing, these obstacles can delay insights and experimental success.
CellRaft Technology will help you overcome these limitations, transforming your approach to forming and growing colonies with the edits you want.
How CellRaft Technology Overcomes These Challenges
- Improving monoclonal colony formation from fragile edited cells.
- Using a single consumable that enables screening thousands of cells for the edits you want via automated image acquisition and software-driven analysis.
- Isolating cells using our innovative and gentle, fluidics-free approach.
How We’re Different:
- Our proprietary consumable enables superior single cell growth by allowing cells to share media while remaining physically isolated, unlike traditional single-cell-per-well methods.
- We pick colonies, not single cells, so the 96 well plates are filled with viable clones that continue to expand rapidly.
- We can identify even rare edits from minimal cell inputs that are not feasible in fluidics-based instrumentation.
- We offer the ability to screen 40,000 cells (equivalent to 416 96-well plates).
Challenges with Cell Line Development for Gene-edited Cells
- Low cell viability post-isolation
- Requires significant reagent and plastic use
- Laborious manual screening and manipulation
- Low editing efficiency
- Multiple pieces of expensive equipment needed

More is made up of thousands of microwells called CellRafts that allow the cells to share a contiguous media volume so that while the cells are segregated, they are not “alone.”
Image CellRafts at Multiple Time Points
Ensuring cells undergoing gene editing grow into clonal colonies is an essential component of the editing workflow. Using the CellRaftA microscale polystyrene growth surface within an array used to spatially segregate cells/colonies while maintaining shared media access, enabling imaging over time and targeted isolation. More AIR® system, single cells can be imaged and tracked over the course of colony formation. In addition, the knockout phenotypes (elimination of GFP and RFP signal) can be tracked over time which provides a unique capability for phenotypic gene editing screening.
