Abstract
The present disclosure provides instruments, modules and methods for improved detection of edited cells following nucleic acid-guided nuclease genome editing. The disclosure provides improved automated instruments that perform methods—including high throughput methods—for screening cells that have been subjected to editing and identifying cells that have been properly edited.
Claims20
A singulation assembly for a solid wall isolation, incubation and normalization (SWIIN) module comprising:
- a retentate member comprising;
- an upper surface and a lower surface and a first and second end,
- an upper portion of a serpentine channel defined by raised areas on the lower surface of the retentate member, wherein the upper portion of the serpentine channel traverses the lower surface of the retentate member;
- and
- at least one retentate port fluidically connected to the serpentine channel;
- and
- a permeate member:
- an upper surface and a lower surface and a first and second end,
- a lower portion of the serpentine channel defined by raised areas on the upper surface of the permeate member, wherein the lower portion of the serpentine channel traverses the upper surface of the permeate member, and wherein the lower portion of the serpentine channel is configured to mate with the upper portion of the serpentine channel to form the serpentine channel;
- at least one permeate port fluidically connected to the serpentine channel;
- a perforated member comprising at least 100,000 perforations disposed under and adjacent to the retentate member, wherein a volume of a well formed by a perforation is from 1-15 nl;
- a filter disposed under and adjacent to the perforated member and above and adjacent to the permeate member;
- and
- a gasket surrounding the filter.
