Paper Oligoarginine-Bearing Tandem Repeat Penetration-Accelerating Sequence Delivers Protein to Cytosol vi
Peptide r12
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence no
Peptide Concentration Final to cells typically 20 µM CPP (after 45 min treatment; see Figure 2b/Methods).
Rna Concentration
Mixing Ratio Simple mixing with protein cargo (e.g., EGFP:CPP 15 µM : 20 µM final to cells).
Formulation Format Noncovalent CPP/protein complexes by simple mixing + incubation (no cross-linking required).
Formulation Components CPP + protein cargo (EGFP or IgG) in Opti-MEM; then DMEM added for incubation.
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells HEK293
Animal Model
Administration Route
Output Type protein cytosolic delivery (not RNA delivery)
Output Value Does not deliver EGFP to cytosol (similar to EGFP alone under these conditions).
Output Units
Output Notes Used as comparator CPP in EGFP delivery experiments.
Toxicity Notes MTT: mild viability decrease with increasing Pas2r12 concentration (e.g., ~85% at 20 µM; ~68% at 30 µM) in EGFP delivery condition.
