| Size Nm | |
| Zeta Mv | |
| Model Scope | in_vitro |
| Model Type | in vitro |
| Cell Lines Or Primary Cells | Huh-7-Luc (luciferase-expressing human hepatoma cells; 10% FBS media) |
| Animal Model | |
| Administration Route | |
| Output Type | Uptake (flow cytometry + fluorescence microscopy) and RNAi (luciferase assay, 24 h) |
| Output Value | No significant luciferase knockdown at N/P=4 (24 h). |
| Output Units | |
| Output Notes | Moderate intracellular Alexa488-siRNA signal by microscopy; flow cytometry shows intermediate mean fluorescence. RNAi measured in 10% FBS at 24 h; Lipofectamine 3000 ineffective under these conditions. |
| Toxicity Notes | Low cytotoxicity at N/P=2–8 (24 h) in viability assay. |
