Pectin NPs and Pectinal Melittin physical stability pattern. Three stability factors were investigated: average particle size (A), PDI (B), and EE% (C) of pectin NPs and average particle size (D), PDI (E), and EE% (F) of pDNA/Melittin/pectin. The results are shown as mean ± SD (n = 3). *P < 0.05, **P < 0.01
