Peptide WRAP5
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence medium
In Vitro Functional Effect yes
Endosomal Escape Evidence yes
Peptide Concentration Peptide:siRNA molar ratio R = 20; peptide concentration not separately reported.
Rna Concentration 5, 10, 20, or 50 nM siRNA final concentration
Mixing Ratio WRAP5:siRNA molar ratio R = 20; preincubated 30 min at room temperature in 5% glucose.
Formulation Format peptide-based nanoparticle / non-covalent CPP:siRNA complex
Formulation Components WRAP5:siRNA peptide-based nanoparticles formulated in 5% glucose; peptide:siRNA molar ratio R = 20; siFluc or siSCR; fluorescent siFluc-Alexa790/Cy3 included for imaging in some experiments.
Size Nm 80.00
Zeta Mv 28.80
Model Scope in_vitro
Model Type in vitro reporter-gene silencing
Cell Lines Or Primary Cells U87-CMV/Fluc+Nluc+ and U87-CMV/Fluc-IRES-Nluc human glioblastoma reporter cell lines
Animal Model
Administration Route cell culture transfection; 1.5 h serum-free incubation followed by serum-containing medium
Output Type in vitro functional reporter knockdown
Output Value Dose-dependent Fluc silencing; Nluc unchanged when encoded on separate mRNA; both Fluc and Nluc decreased when encoded on common mRNA, supporting RNAi-mediated mRNA degradation.
Output Units
Output Notes This row captures in vitro functional siRNA delivery. It is not an in vivo delivery success even though the reporter knockdown was functional in cells.
Toxicity Notes WRAP5:siSCR did not inhibit Fluc; authors report no toxicity of the PBN formulation in vitro.
