Experiment: Delivery of unmodified, phosphorothioate (PS)-stabilized crRNA with chemically modified, PS-stabilized tracrRNA using the S10 shuttle peptide to activate the mTmG reporter in mouse brain
PI: Erik J Sontheimer, PhD
Description: Chemically modified crRNA and tracrRNA were injected into the intra-striatum of mTmG reporter mice and activation of GFP expression was imaged.
Editing Assay:
Editing efficiency determined by immunohistochemical staining for GFP.
