  1. All experiments were conducted in triplicate, and the data are presented as mean values ± SD.
  2. aFor PAEMA and PMAA, the values are determined using Eq. (2) in the “Methods” section. For protamine, the value indicates the number of amino acids in the primary sequence.
  3. bFor PAEMA and PMAA, the average molecular weights were determined using Eq. (1) in the “Methods” section. The average molecular weight was determined as per the manufacturer’s specifications.
  4. cSASA calculations were performed on a pentamer, with polyarginine serving as the basis for protamine analysis, as detailed in the “Methods” section.
  5. dThe solubility of protamine was determined through turbidity measurements, which marked the transition from a two-phase to a one-phase solution.
