CUY21SC (CUY21 Electroporator)

We developed a new electroporator CUY21SC with the following features based on our long time (more than 30 years) experience from the various types of electroporation (electric gene transfer) projects.

CUY21EDIT (CUY21 Electroporator) Features

Superior electrical control brings you success in gene transfer.

In Vivo, In Ovo, In Utero, Ex Vivo Electroporator CUY21SC (CUY21)

CUY21SC (CUY21 electroporator) is designed especially for sensitive in vivo, in ovo, in utero and ex vivo electroporation.

Automated Sensitive Current Measurement

CUY21SC (CUY21 electroporator) can measure the electric current from the low ampere (1mA) up to 1.60A. Current is the major factor to obtain successful electroporation results. Initially CUY21SC (CUY21 electroporator) was developed for the electroporation in which genes are delivered into the sensitive target such as mouse's brain, embryo, tissue slice and chick embryo. In those sensitive applications, low current is required to avoid the damage on a cell or brain etc. This CUY21 Electroporator makes it possible to measure and display such current automatically. The output current information remarkably helps you optimize your electroporation experiments.

Impedance Measurement

CUY21SC (CUY21 electroporator) easily enables you to measure impedance (electric resistance) of the target sample and automatically displays it. The fluctuation in resistance value results in changes in current value and as a result it affects the reproducibility of experiments. In order to deliver the optimal current, you need to know the actual resistance of the target sample before electroporation. Because in vivo resistance is less stable than in vitro in general, the impedance value which is measured prior to in vivo electroporation is the important criteria to determine whether the experiment is going well.

Accurate Low Voltage Square Wave Pulses

CUY21SC (CUY21 electroporator) is designed to output precise low voltage square wave pulses. The accurate and low voltage square wave pulses bring high transfection efficiency and less damage. Therefore, in the usage of this CUY21 Electroporator, the low voltage range can cover almost all in vivo, in utero, in ovo and ex vivo applications unlike other electroporators.

Wide Applications In Combination With A Variety of CUY Series Electrodes

CUY21SC (CUY21 electroporator) can be used with more than 250 NEPA GENE's CUY series electrodes which make it possible to do a wide range of electroporation experiments. And custom-made electrodes are easily ordered and available for this CUY21 electroporator. It enables you to realize the experiments which you have actually desired.

Safety Function

For safety operation, the safety limit function is built in CUY21SC (CUY21 electroporator). To prevent unexpected electrical accidents, electroporation program stops immediately and automatically in case that the excess current (> 1.60A) flows.

Voltage Measurement

CUY21SC (CUY21 electroporator) is able to perform the voltage measurement which is the useful function that measures the actual voltage of the first DC pulse. By checking the voltage, it is easy to find out whether programmed voltage of DC pulse is generated. If not, there is something wrong with a device.

LED Display

There are seven LED displays on CUY21SC (CUY21 electroporator) front panel. Each parameter of the electroporation program is displayed on the independent LED. In addition, the measured voltage and current are also displayed on this CUY21 Electroporator immediately after the electroporation.

Compact and Stylish

CUY21SC (CUY21 electroporator) is a compact and sophisticated design.
