Automated cell processing methods, modules, instruments, and systems comprising flow-through electroporation devices
In an illustrative embodiment, automated multi-module cell editing instruments comprising one or more flow-through electroporation devices or modules are provided to automate genome editing in live cells.
1. A reagent cartridge comprising:
a cartridge body;
a plurality of receptacles disposed within the cartridge body configured to receive tubes and vials;
a flow-through electroporation (FTEP) module disposed within the cartridge body configured to introduce nucleic acids into cells, wherein the FTEP module comprises:
a. an inlet and an inlet channel for introducing a fluid comprising cells and exogenous material into the FTEP module;
b. an outlet and an outlet channel for removing a fluid comprising transformed cells and exogenous material from the FTEP module;
c. a flow channel intersecting and positioned between the inlet channel and the outlet channel; and
d. two or more electrodes positioned in the flow channel between the intersection of the flow channel with the first inlet channel and the intersection of the flow channel with the outlet channel; wherein the electrodes are in fluid communication with fluid in the flow channel but are not in the direct flow path of the cells in the flow channel; and wherein the electrodes apply one or more electric pulses to the cells in the fluid as they pass through the flow channel, thereby introducing the exogenous material into the cells in the fluid;
machine-readable indicia disposed upon the cartridge body for identifying contents of tubes and vials disposed in the receptacles and for operating the FTEP, wherein the machine-readable indicia is configured to be read by a processor;
connection to a pressure control system, wherein the pressure control system pulls cells from the inlet toward the outlet and pushes cells from the outlet toward the inlet one to several times; and
a cover for the cartridge body to secure tubes and vials disposed within the reagent cartridge.
2. The reagent cartridge of claim 1 wherein the FTEP module further comprises a reservoir connected to the inlet for introducing the cells in fluid into the FTEP module and a reservoir connected to the outlet for removing transformed cells from the FTEP module.
3. The reagent cartridge of claim 1 wherein the FTEP module further comprises a second inlet and a second inlet channel and further comprising a reservoir connected to the second inlet for introducing the exogenous material into the FTEP module.
4. The reagent cartridge of claim 3 wherein the second inlet and second inlet channel of the FTEP module are located between the inlet and inlet channel and the electrodes of the FTEP module.
5. The reagent cartridge of claim 3 wherein the second inlet and second inlet channel of the FTEP module are located between the electrodes and the outlet channel and outlet of the FTEP module.
6. The reagent cartridge of claim 1 wherein the electrodes in the FTEP module are spaced from 10 micrometers to 5 mm apart.
7. The reagent cartridge of claim 1 wherein the FTEP module further comprises a filter between the inlet channel and the electrodes.
8. The reagent cartridge of claim 1 , wherein device is configured for use with bacterial, yeast and mammalian cells.
9. The reagent cartridge of claim 1 , wherein one or more of the receptacles comprises a tube insert configured to accommodate small tubes.
10. The reagent cartridge of claim 1 , comprising at least seven receptacles.
11. The reagent cartridge of claim 1 , comprising at least seven receptacles.
12. The reagent cartridge of claim 11 , comprising at least 15 receptacles.
13. The reagent cartridge of claim 1 , wherein the reagent cartridge is part of a kit.
14. The reagent cartridge of claim 13 , wherein the kit comprises reagents disposed within the receptacles.
15. The reagent cartridge of claim 14 , wherein the reagents disposed within the receptacles are reagents to perform nucleic acid-guided nuclease editing.
16. A kit comprising the reagent cartridge of claim 1 .
17. The kit of claim 16 wherein the reagents comprise three or more of a library of editing oligonucleotides in a vector backbone, cells, a wash solution, an enzyme, a cell culture medium and a buffer.
18. The kit of claim 16 wherein the reagents comprise four or more of a library of editing oligonucleotides in a vector backbone, cells, a wash solution, an enzyme, a cell culture medium and a buffer.
19. The kit of claim 16 , wherein the machine-readable indicia disposed upon the cartridge body further provides instructions for movement of a robotic handling system.
20. The kit of claim 16 , wherein each receptacle is separately labeled with machine-readable indicia.
