Peptide PepFect6 (PF6)
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence
Peptide Concentration Set by molar ratio 40 (CPP:siRNA). Exact µM peptide depends on siRNA concentration.
Rna Concentration 2D monolayer: 100 nM siRNA final in medium
Mixing Ratio CPP/siRNA NPs formed at molar ratio 40 (CPP:siRNA) by mixing peptide + siRNA in MilliQ water (pH 5.3–6.3) and incubating 45 min at room temperature before transfection.
Formulation Format CPP/siRNA nanoparticles (noncovalent electrostatic NPs)
Formulation Components PepFect6 (PF6) + siRRM2
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells U-87MG human glioblastoma cells (2D monolayer)
Animal Model
Administration Route
Output Type Functional RNA effect: RRM2 mRNA knockdown (qRT-PCR, 48 h), RRM2 protein decrease (ICC), cell-cycle arrest (PI-FACS), reduced invasion (Matrigel).
Output Value
Output Units
Output Notes Significant RRM2 knockdown vs pure siRRM2; RRM2 protein decreased by immunocytochemistry; G1/S cell-cycle arrest and strong reduction of invasiveness reported. Reported (from prior characterizations): ~30–40 nm (TEM) and ~100–200 nm (DLS) when complexed with siRNA (not newly measured in this paper).
Toxicity Notes Authors reference prior cytotoxicity characterization for PF6/NF70 at similar conditions; current work focuses on knockdown and phenotypic assays (migration/invasion/proliferation).
