Polydispersity

A distribution of molecular masses rather than a single value. Characteristic of synthetic polymers and therefore of PEG conjugates.

Related terms

PEGylation
Covalent attachment of polyethylene glycol. The polymer is polydisperse, so a PEGylated peptide has no single mass and no meaningful single purity figure.
