Immobilized IgG binding proteins and the use thereof to effect affinity chromatography and separate the subclasses of IgG. Disclosed are cysteine-containing IgG binding proteins which have high binding capacity for human IgG and mouse monoclonal IgG.

Immobilized protein G variants and the use thereof

A process for the recovery and purification of L-asparaginase from Erwinia chrysanthemi is disclosed. The process involves the preparation of cellular acetone powder extract followed by either an ion exchange and affinity chromatography purification steps or by affinity chromatography alone. The column eluent is then dialyzed to produce substantially pure L-asparaginase.
