Super Electroporator NEPA21 Type II



NEPA21 Novel 4-Step Multiple Electroporation Pulsing

NEPA21 pulse waveform(x: time y: voltage)

The novel 4-step pulsing with voltage decay results in higher transfection efficiency and higher viability WITHOUT special buffers.

  1. Poring Pulse Mode:
    • Higher voltage, shorter duration, multiple pulses, voltage decay; This is for forming pores (small holes) in cell membrane with minimum damage.
  2. Polarity Exchanged Poring Pulse
    • This can be applied to tissue transfection as well.
  3. Transfer Pulse Mode:
    • Lower voltage, longer duration, multiple pulses, voltage dcay; This is for delivering the target molecules (DNA, RNA, etc.) into cells with minimum damage.
  4. Polarity Exchanged Transfer Pulse
    • This can increase the transfection efficiency.

Compare with other companies' devices

Is your lab still using a transfection device that requires expensive disposable kits?
We hear from many researchers that they are not happy with how much it costs to run.

Numerous achievements: in vivo electroporation, zygote electroporation for genome editing and more

NEPA21 can be used not only for cell culture electroporation, but also for many in vivo gene transfer applications in animals such as mice and rats, including zygote electroporation for the production of genetically modified organisms (GMOs).

Accurate and precise measurement of sample electrical resistance and electroporation pulse voltage, current, and power

In the electrical pulses of electroporation, the parameters of Ohm’s law – “voltage”, “current” & “resistance” – have a great influence on the experimental results. The reproducibility of the same “voltage”, “current” & “resistance” for each electroporation is important to achieve stable gene transfer results. Since the NEPA21 can measure the resistance, output the voltage and measure the current with great accuracy, it can control these factors.

The NEPA21 also provides a measure of electrical pulse power in joule.

By knowing more about the electrical parameters of electroporation, it is now possible to achieve more optimal electrical conditions for each application.
