| Experiment Id | EXP001983 |
|---|---|
| Paper | Bi-specific splice-switching PMO oligonucleotides conjugated via a single peptide active in a mouse |
| Peptide | Pip6a-PMO (Dmd exon23) single conjugate |
| Delivery Success Class | no |
| In Vivo Flag | no |
| Uptake Confirmed | no |
| Label Confidence | high |
| In Vitro Functional Effect | yes |
| Endosomal Escape Evidence | |
| Peptide Concentration | 0.5–1 µM conjugate (serum-free Opti-MEM, 4 h transfection; then DMEM/5% horse serum 20 h). |
| Rna Concentration | Same as conjugate concentration (PMO content equimolar to conjugate; for bi-specific constructs total PMO per conjugate contains two PMOs). |
| Mixing Ratio | Covalent 1:1 Pip6a:PMO conjugate (amide bond to 3′ secondary amine of PMO). |
| Formulation Format | Covalent CPP–PMO conjugate (P-PMO); bi-specific constructs carry two PMOs on one CPP via amide + triazole (click) or disulfide linkages. |
| Formulation Components | Pip6a CPP conjugated to PMO(s): Dmd exon23 PMO and/or Acvr2b exon5 PMO (see construct-specific linkage notes). |

| Model Scope | in_vitro |
| Model Type | in vitro |
| Cell Lines Or Primary Cells | H2K/mdx mouse myoblasts differentiated to myotubes (mdx dystrophin model) |
| Animal Model | |
| Administration Route | |
| Output Type | In vitro functional RNA effect: exon skipping (RT-PCR) for Dmd exon 23 and Acvr2b exon 5 |
| Output Value | High, dose-dependent Dmd exon 23 skipping at 0.5–1 µM (RT-PCR). |
| Output Units | |
| Output Notes | Used as reference control; slightly higher skipping than some bi-specific constructs. |
