The Neon Transfection System is a pulse generator, able to deliver longer microsecond pulses used in gene electrotransfer treatments. The cell suspension is transferred to a special tip which contains one gold electrode. Tip is mounted on a special pipette which is inserted in the electroporation chamber which contains the other electrode. The gap between the electrodes is maximized while the surface area is minimized to reduce pH changes and heat generation. The generator comes with predefined protocols and electroporation buffers for efficient gene transfection. Special tips and electroporation chambers are packed separately and enable sterile environment. The parameters of electric pulses can be easily changed via the touchscreen.
