Abstract:
Systems, methods and algorithms for automatically performing optimization of an electroporation system. A system according to the present invention typically includes a cuvette holding assembly (80) configured to hold a plurality of electroporation cuvettes (85), wherein each cuvette includes a first and second electrode, and a shocking chamber (75) configured to hold the cuvette holding assembly, the chamber having a commutator assembly configured to provide an electrical contact to the first electrode of each of the plurality of cuvettes in turn. The system also typically includes a control system communicably coupled to the shocking chamber, wherein the control system controls the commutator (100) to automatically contact the first electrode of each cuvette in an order and to provide a potential across the cuvette electrodes when contact is made.
Abstract:
Cuvette inserts adapted and configured to fit within an electroporation cuvette. The inserts each include a support structure that holds a porous membrane. When positioned within the cuvette, the membrane is positioned proximal the cuvette electrodes to facilitate membrane-based fusion of cells. In certain aspects, a tube extends through the support structure to allow for application of negative pressure in a convenient location away from electrode contacts and other components of the cuvette or cuvette holder.
Abstract:
Individual temperature control in multiple reactions performed simultaneously in a spatial array such as a multi-well plate is achieved by thermoelectric modules with individual control, with each module supplying heat to or drawing heat from a single region within the array, the region containing either a single reaction vessel or a group of reaction vessels.
Abstract:
An electroporation system and method for directing high-voltage currents to a suspension of cells contained in a cuvette. A high-voltage switch controls the coupling of a charge control to a high-voltage capacitor and, additionally, controls the coupling of the high-voltage capacitor to the cuvette. A current diverter diverts current away from the sample whenever an arc condition commences or a low sample resistance is detected across the cuvette. The current diverter includes a current diverter switch, which is triggered when a sense resistor measures a second predetermined voltage indicative of an arc-over event (or a low sample resistance condition).
