PEG linkers are widely used in peptide synthesis, bioconjugation and drug development. Their hydrophilic and flexible nature improve solubility, provide molecular spacing and help reduce aggregation and steric interactions. PEGylation can be used to modify the properties of peptide therapeutics, including their stability and circulation behaviour. (Ma et al., 2025) Not all PEGs are made … Read more
