| Uptake Confirmed | yes |
| Label Confidence | medium |
| In Vitro Functional Effect | yes |
| Endosomal Escape Evidence | |
| Peptide Concentration | 5 µM (CPP-PNA conjugate) |
| Rna Concentration | 5 µM (PNA conjugate), 1 h treatment; readout after 16 h |
| Mixing Ratio | covalent disulfide conjugate (N/A) |
| Formulation Format | CPP–PNA covalent conjugate (disulfide-linked) |
| Formulation Components | Pen-PNA (antisense 705 PNA) disulfide-linked conjugate |
| Size Nm | |
| Zeta Mv | |
| Model Scope | in_vitro |
| Model Type | in vitro |
| Cell Lines Or Primary Cells | HeLa pLuc 705 (splice correction luciferase reporter) |
