    摘要: A method of measuring acidic species generated by degradation of a Fab or Fab′ component of a Fab-PEG or a Fab′-PEG comprising the steps of: a) cleaving the PEG and linker from the Fab-PEG or Fab′-PEG with an enzyme; b) optionally separating the PEG and linker generated in step a) from the Fab or Fab′, to provide a Fab or Fab′; and c) quantitatively analyzing acidic species associated with the cleaved Fab or Fab′ and/or the cleaved PEG.

    摘要: A method of measuring acidic species generated by degradation of a Fab or Fab′ component of a Fab-PEG or a Fab′-PEG is provided. The method involves: a) cleaving PEG and a linker from the Fab-PEG or Fab′-PEG with an enzyme; b) optionally separating the PEG and linker from the Fab or Fab′ to provide isolated Fab or Fab′; and c) quantitatively analyzing acidic species associated with the cleaved Fab or Fab′ and/or the cleaved PEG.

    摘要: Hybrid proteins are described which comprise one or more antigen-binding antibody fragments covalently linked to one or more serum carrier proteins. The hybrid proteins can bind antigens, have a long half-life in vivo and can be used in medicine for therapy and diagnosis.
