    摘要: This invention is a method of using a class of excipients for protein formulation to reduce and/or eliminate protein aggregation in solutions or solids. This class of compounds contains carbonyl group(s) to form Schiff base(s) with amino groups of proteins and also contains moieties to keep protein molecules spatially separated. This method has never been disclosed anywhere in the literature.
