The presence of PEG linkers between the antibody and payload can influence the properties of the ADCs [1]:

  • Modulate the physicochemical properties, such as balance the payloads’ hydrophobicity, improve solubility, increase DAR, and reduce aggregation
  • Modify the Pharmacodynamic properties, such as increase the rate of payload release and increase invitro cytotoxicity
  • Optimize the pharmacokinetic properties, such as clearance, half-life, and biodistribution
