Paper Effective In Vivo Topical Delivery of siRNA and Gene Silencing in Intact Corneal Epithelium Using a
Peptide QN-Palm-POD / siRNA polyplex
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence yes
Peptide Concentration
Rna Concentration
Mixing Ratio 140:1 (QN-Palm-POD:siRNA) for full complexation; example transfection uses 17.5 µM QN-Palm-POD + 125 nM siRNA.
Formulation Format CPP–siRNA polyplex with covalently attached endosomal disruptor analog
Formulation Components QN-Palm-POD complexed with siRNA (140:1) in PBS.
Size Nm 107.00
Zeta Mv 14.90
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells HCE-S human corneal epithelial cells
Animal Model
Administration Route
Output Type In vitro functional RNA effect (luciferase knockdown) + uptake imaging
Output Value ~50% luciferase knockdown in vitro; >90% cells show siGLO-positive signal.
Output Units
Output Notes siGLO pattern suggests improved endosomal release vs Palm-POD alone (smaller/less defined puncta).
Toxicity Notes MTT: ~80% viability at 9–35 µM; transfections used reduced concentrations to balance complexation and toxicity.
Curation Notes
