Sequence: DDDDDD
| Experiment Id | EXP002426 |
|---|---|
| Paper | Peptide codes for organ-selective mRNA delivery |
| Peptide | 6D-LNP / Cas9 mRNA + sgPten |
| Delivery Success Class | yes |
| In Vivo Flag | yes |
| Uptake Confirmed | no |
| Label Confidence | high |
| In Vitro Functional Effect | |
| Endosomal Escape Evidence | |
| Peptide Concentration | not separately reported; DSPE-PEG-peptide included by molar ratio in LNP formulation |
| Rna Concentration | 1.5 mg/kg ASO i.v. on days 0, 1 and 2 |
| Mixing Ratio | Ionizable lipid/ASO ratio fixed at 15/1 (wt/wt) |
| Formulation Format | Peptide-modified lipid nanoparticle (POST-LNP) |
| Formulation Components | POST-LNP: ionizable lipid (mostly MC3 unless noted), cholesterol, DSPC/helper lipid, DSPE-PEG-peptide, DSPE-PEG, and encapsulated RNA; standard molar ratio 50:38.5:10:6:0.75 unless otherwise specified. |
| Size Nm | 148.40 |
| Zeta Mv | -54.60 |
| Model Scope | in_vivo |
| Model Type | in vivo |
| Cell Lines Or Primary Cells | |
| Animal Model | ICR-Tg(CAG-EGFP) mice |
| Administration Route | Intravenous injection |
| Output Type | Spleen-selective EGFP-ASO silencing |
| Output Value | organ-selective reduction of EGFP fluorescence |
| Output Units | |
| Output Notes | Functional in vivo RNA effect (ASO-mediated silencing) was demonstrated. uptake_confirmed left NaN because direct ASO uptake was not separately measured for this row. |
| Toxicity Notes | POST-LNPs showed minimal organ toxicity by H&E at high Luc mRNA dose compared with LPS; no explicit toxicity issue reported for curated rows. |
