Administration Route
Output Type Reporter expression (luciferase) ± uptake (Cy5-pDNA flow cytometry/CLSM)
Output Value High transfection; increases with N/P; superior to jetPEI.
Output Units
Output Notes Pep2–Pep4 showed higher pDNA transfection efficiencies than other peptides and jetPEI; Pep2/Pep3 decreased with higher N/P, Pep4 increased with higher N/P. Time-course with gLuc pDNA showed continued increase/plateau through 72 h.
Toxicity Notes Cytotoxicity ranking reported: Pep5 > Pep2, Pep3, Pep7 > Pep4, Pep6 > Pep1 (24 h viability assay).
