摘要： The present invention relates to a method of separating one or more immunoglobulin containing proteins from a liquid. The method includes first contacting the liquid with a separation matrix comprising ligands immobilised to a support; allowing the immunoglobulin containing proteins to adsorb to the matrix by interaction with the ligands; followed by an optional step of washing the adsorbed immunoglobulin containing proteins; and recovering said immunoglobulin containing proteins by contacting the matrix with an eluent which releases the proteins. The method improves upon previous separation methods being that each of the ligands consists essentially of a monomer or dimer SpA or protein Z or a functional variant thereof.

摘要： The present invention relates to a method for reducing total sample complexity in native or digested biological sample(s), before analysis thereof by mass spectrometry, comprising the following steps: a) selecting a fraction from the entire native or digested biological sample(s) on the basis of pi-value, said fraction comprising native or digested sample representing a subset of or the entire substance population in the sample; b) separating native or digested sample substances from each other; and c) analysing said substances by mass spectrometry. The invention also relates to a system for reducing total sample complexity in the above method, comprising a high capacity charge-selective column coupled to a MDLC work flow path comprising a cation exchange column and a RPC column. The system is followed by a MS/MS instrument.
