Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells A549; A549-Luc (luciferase-expressing A549)
Animal Model
Administration Route
Output Type reporter knockdown (luciferase)
Output Value 15% suppression after extended incubation (48 h); no knockdown at 24 h under standard condition
Output Units
Output Notes Uptake/CLSM: strong uptake in A549; predominantly punctate fluorescence; strong colocalization with LysoTracker (endosomal/lysosomal localization). RNAi: no effect at 24 h post-treatment (8 h incubation + 24 h culture) even at ratios 100/50/20; extending culture to 48 h gave ~15% suppression; 72 h reduced again.
Toxicity Notes No significant LDH release reported vs control at 1.0 µM/10 nM (ratio 100).
