  • Process for the conjugation of a peptide or protein with a reagent comprising a leaving group including a portion of PEG
    Patent number: 10835616
    Abstract: The invention relates to novel conjugating reagents capable of reaction with at least one nucleophile present in a peptide or protein, which contain at least one leaving group which is lost on reaction with said nucleophile, in which the leaving group includes a portion —(CH2CH2O)n—, in which n is a number of six or more; and novel processes for the preparation of conjugates containing peptides or proteins made using such reagents.
    Type: Grant

  • NOVEL CONJUGATED PROTEINS AND PEPTIDES
    Publication number: 20100239517
    Abstract: The invention provides a novel process for conjugating a polymer, especially PEG, to a protein or peptide, which comprises reacting a polymeric conjugation reagent with a protein or peptide containing a polyhistidine tag under conditions such that conjugation occurs via said polyhistidine tag. The resulting conjugates are novel.
