Abstract
Source: Chuan, Y. et al. Novel method of plasmid DNA delivery to mouse bladder urothelium by electroporation. J. Vis. Exp. (2018)
This video demonstrates the delivery of DNA plasmid into the urothelium of the mouse bladder using a combination of urethral catheterization and electroporation techniques. The described procedure allows the generation of mouse bladder cancer models.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Plasmid and Tools Preparation For each bladder to transfect, prepare at least 20 µL of DNA plasmid (1 µg/µL). Add 1 µL of Trypan Blue to the 20 µL of plasmid solution in a 1.5 mL microcentrifuge tube. Pipette to mix well. Autoclave all surgical instruments and sterilize the w…
