Endosomal Escape Evidence
Peptide Concentration 0.3–1.0 µM (depends on MR; oligo 100 nM)
Rna Concentration 100 nM
Mixing Ratio MR 3:1, 7:1, 10:1 (peptide:D-arm ASO)
Formulation Format non-covalent peptide/oligonucleotide nanocomplex
Formulation Components Peptide + oligonucleotide in MilliQ water (10% final volume), incubated 1 h RT; added to cells in complete medium
Size Nm 50.90
Zeta Mv 17.50
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells HeLa pLuc705
Animal Model
Administration Route
Output Type mitochondrial membrane potential (TMRE)
Output Value Stronger TMRE effects vs unmodified ASO; up to ~20× TMRE uptake after 24 h (some peptides)
Output Units
Output Notes D-arm modification alone increased uptake; peptide complexes further perturbed mitochondrial membrane potential.
Toxicity Notes WST-1: >80% cell viability (tested MRs)
Curation Notes
