3rd version of Genome Editor series! An Electroporator to perform DNA-Free genome editing

 

Cat#:GEBPL
Product Name: Genome Editor for Plants
Manufactured by:BEX CO.,LTD.

 

New technology of innovative electrical pulse, developed by BEX achieves highly efficient delivery of Cas9 to protoplasts.

 

 

New electrical pulse pattern: Fall pulse <patent applied!> 

New and innovative technology to make an instant change from + charge to - achieves more efficient delivery than ordinary electroporation.

 

FallPulse

 

Highly efficient genome editing by gRNA and Cas9 (RNP)

We succeeded in knock-in for plants as well as knock-out.

 

5.7-inch touch panel for easy use

Genome Editor for plants is operated by 5.7 inch touch panel. It is very easy to operate Genome Editor for plants  visually by the  touch panel. The visual operation avoids the mistakes of which parameter to be set.

 

Compact body

Genome Editor for plants is desktop-size, easy-to-move.   

 

All data of executed voltage and current pulses are recorded.

Genome Editor for plants automatically records the last 100 runs of data of executed volatege and current. It is not necessary to make a note of values of each electroporation. This function makes the experiments more efficient. Genome Editor for plants displays the executed parameter and can generate the same parameter as the displayed parameter. 

 

  

 

Application

GFP plasmid DNA delivery to tobacco cells (protoplasts) 

 

Comparison between previous pulse pattern and fall pulse pattern for tobacco protoplast electroporation 
Fall Pulse. Fall pulse perfroms highly efficient delivery of GFP plasmid DNA.

FallPulseComparison

 
 

 Knockout of PDS (Phytoene desaturase) gene of to tobacco cells (protoplasts)

 

Auto-fluorescene specific in plants is note detected as PDS gene is knockout by design of gRNA on phytoene desaturase gene of Carotenoids biosynthesis

 

PDSknockout

 

PDSknockout2

In comparison with control, green color on the plant disappears in the bright field as well as auto-fluorescene.

 

 

Knock-in of dsDNA to tobacco cells

 

dsDNA with GFP cassette is electroporated with gRNA and Cas9 to tobacco cells (protoplasts). After regeneration, GFP fluorecene is detected.
