主权项 1. A process for preparing a composition of a pegylated therapeutic protein, wherein in said composition at least 61 percent of the mono pegylated therapeutic protein fraction comprised in said composition is N-terminally mono-pegylated therapeutic protein, comprising the step of: reacting in an aqueous medium a therapeutic protein with a water-soluble polyethylene glycol under conditions of a reductive alkylation, characterized in that the reaction is performed within a pH range of about 6.5 to 7.5, to provide the composition of the pegylated therapeutic protein.
