摘要： High purity protein A is recovered from protein A preparations by passing a protein A preparation over an ion exchange column so that protein A will bind to a cation exchange resin. The loaded column is washed with a wash buffer solution having about the same pH as the protein A preparation and an increased mineral salt concentration to elute certain impurities but not the protein A. The protein A is eluted from the washed column by eluting the column with an elution buffer solution having a pH higher than the wash buffer solution and mineral salt concentration substantially no higher than the wash buffer solution. The protein A can be easily recovered from protein A preparations that do not use any human or animal components. The protein A purified by the invention is suitable for all common uses of protein A, but is especially well-suited for human therapeutic applications.

摘要： The present invention provides methods for analyzing a target compound from a biological sample. In one aspect, a method for analyzing a target compound in a biological sample can comprise delivering a biological sample through an affinity column, the affinity column having a binding ligand coupled to a stationary structural support, wherein the affinity column has a high density of the binding ligand per the stationary structural support and wherein the binding ligand has been preselected to cause weak affinity separation zonal retardation of the target compound from the biological sample forming a target compound fraction and a biological sample fraction and detecting the target compound by mass spectrometry.

摘要： The present invention provides methods for separating proteins from a protein mixture. In one aspect, a method for separating a high concentration protein mixture into a bound protein fraction and a flow-through protein fraction can include delivering a protein mixture through an ion exchange column at a fixed pH and a fixed salt concentration. The fixed pH and the fixed salt concentration have been preselected to cause separation of the protein mixture into a bound protein fraction and a flow-through protein fraction. In this case, the bound protein fraction binds to the ion exchange column and the flow-though protein fraction flows though the ion exchange column. The method can further include receiving the flow-through protein fraction from the ion exchange column separate from the bound protein fraction, wherein either the bound protein fraction or the flow-through fraction contains a protein of interest.
