More Information
Summary:The present disclosure provides materials and methods for determining the presence of an N-terminal modification on a therapeutic protein, and/or the efficiency of N-terminal modification, such as PEGylation, at the N-terminus of a therapeutic protein such as Filgrastim (wherein the PEGylated version is therefore Pegfilgrastim).
