Paper Identifying Antisense Oligonucleotides to Disrupt Small RNA Regulated Antibiotic Resistance via a Ce
Peptide (KFF)3K
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect no
Endosomal Escape Evidence
Peptide Concentration 6–8 µM final (used as control in reporter/MIC assays)
Rna Concentration 6 µM (control vs 12-1); 6 µM in combo-control; 8 µM tested as higher-dose control
Mixing Ratio N/A (covalent conjugate)
Formulation Format CPP-PNA conjugate (covalent); added directly to E. coli cultures / MIC wells
Formulation Components KFFKFFKFFK-O-ttccgccaactc (SI Table S3)
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells Escherichia coli MG1655 (liquid culture reporter assay and MIC assays)
Animal Model
Administration Route
Output Type reporter fluorescence control; MIC control; growth effect at higher dose
Output Value 6 µM scramble used as control; 8 µM scramble decreased growth rate and also reduced MIC (nonspecific effect)
Output Units
Output Notes Control CPP-PNA scramble used throughout; authors note 8 µM scramble reduced growth rate and reduced MIC, suggesting concentration-dependent nonspecific effects.
Toxicity Notes 8 µM CPP-PNA scramble decreased growth rate; reduction in MIC at 8 µM likely nonspecific.
