報告內容：Successful protein separation by column liquid chromatography depends on a combination of the selectivity and efficiency of the column packing materials used. The lecture will discuss different chromatographic separation principles and methods for protein separation with an emphasis of the chemical structure and function of the most frequently used chromatographic base matrices, polystyrene-divinyl benzene (PS-DVB) and agarose. Progress in increasing the protein binding capacity of agarose gels will also be discussed as well as means to bind extracellular proteins secreted by Pichia pastoris and animal cell culture without the necessity of dilution of the cell culture supernatant.
