Abstract
This invention is directed to processes for reducing the level of free carbohydrate from a solution of protein-linked carbohydrate (conjugate) and non-linked carbohydrate. In this process, the conjugate is adsorbed to a hydrophobic membrane while the carbohydrate is not. The conjugate is then desorbed from the membrane, yielding a solution that is substantially reduced in free carbohydrate.
