Output Notes Relative luciferase activity (RLU/µg protein) after 24 h treatment in OptiMEM ± serum; uptake quantified by flow cytometry (mean fluorescence) using CPP–PMOF.
Toxicity Notes No detectable cytotoxicity up to 10 µM; at higher concentrations (20–60 µM) time- and concentration-dependent toxicity mainly observed for (RX)8–PMO and (RXR)4–PMO; others largely non-toxic in assays reported.
