Conditional Rod Cell Ablation in Xenopus Tadpoles Using the NTR-MTZ System

To begin, use a transgenic line expressing GFP and nitro reductase, or NTR, under a rod photoreceptor specific promoter. NTR converts the prodrug metronidazole, or MTZ, into a cytotoxic agent for selective ablation of NTR expressing rods. For GFP
