| Label Confidence | medium |
| In Vitro Functional Effect | yes |
| Endosomal Escape Evidence | |
| Peptide Concentration | |
| Rna Concentration | pGL3 205 ng/µL (4 µL used in complex prep) |
| Mixing Ratio | Stepwise mixing with ZIF-8 (4 µL of 1 mg/mL) + pGL3 (4 µL); plasmid:ZIF-8 tested 1:0.5 and 1:1; charge ratios 5 and 10 (reported across experiments) |
| Formulation Format | CPP/ZIF-8/RNA polyplex (noncovalent) |
| Formulation Components | PF221 + pGL3 + ZIF-8 |
| Size Nm | 25.00 |
| Zeta Mv | |
| Model Scope | in_vitro |
| Model Type | in vitro |
| Cell Lines Or Primary Cells | HeLa |
| Animal Model | |
| Administration Route | |
| Output Type | Reporter gene expression (luciferase) |
| Output Value | |
| Output Units | |
| Output Notes | No transfection without CPPs. ZIF-8 nanocomposites increased transfection: pGL3-PF14 by ~2–4×; pGL3-PF221 by ~3–8× vs peptide alone (range across ZIF-8 variants and ratios). |
| Toxicity Notes | WST-1 assay in HeLa cells showed no observable toxicity for ZIF-8 composites with or without CPPs under tested conditions (24 h incubation). |
