| Output Type | Reporter expression (luciferase) ± uptake (Cy5-pDNA flow cytometry/CLSM) |
| Output Value | Lower transfection than Pep2–Pep4 and jetPEI under comparable conditions. |
| 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). |
