Experiment: Testing newly chemically modified crRNA and tracrRNA in mTmG mouse embryonic fibroblasts
PI: Erik J Sontheimer, PhD
Description: Chemically modified crRNA and tracrRNA were delivered by electroporation to embryonic fibroblasts harvested from the mTmG reporter mouse. Gene editing was determined by reporter activation.
Editing Assay:
Calculated editing efficiency by flow cytometry analysis of GFP and RFP.
