Paper Safer and efficient base editing and prime editing via ribonucleoproteins delivered through optimize
Peptide ANTP-ABE8e (covalent CPP fusion)
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed no
Label Confidence medium
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration Dose reported as ~4.5 µg ABE RNP per eye for CPP-fusion comparison experiment
Rna Concentration Guide RNA present in RNP; delivered as assembled RNP
Mixing Ratio Direct delivery of CPP-fused ABE8e RNP; formulations included sucrose as described for free RNP experiments
Formulation Format CPP-fused ABE8e RNP (direct subretinal delivery, no LNP)
Formulation Components CPP-fused ABE8e protein + sgRNA (rd12-A6) (+ sucrose/NaCl formulation as indicated)
Size Nm
Zeta Mv
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model rd12 mouse model of Leber congenital amaurosis (Rpe65 nonsense mutation)
Administration Route Subretinal injection (1 µl per eye)
Output Type In vivo functional outcome: retinal function rescue (scotopic flash ERG b-wave) and on-target editing (sequencing of RPE DNA/cDNA)
Output Value
Output Units
Output Notes CPP-fused ABE8e RNPs were evaluated in vivo; ERG rescue and low-percentage on-target editing were detected, but fused CPPs did not substantially improve outcomes compared with unmodified RNP under their conditions.
