    摘要: The present invention relates to a method of isolating a target compound from other components of a liquid, which method comprises at least two chromatographic steps, in any sequence of order, wherein the mobile phase is contacted with an affinity chromatography matrix and/or an ion-exchange chromatography matrix and/or a hydrophobic interaction chromatography matrix, wherein the contacting with at least one of the matrices takes place in the presence of at least one non-ionic polyether; and obtaining the target compound(s) in a separate fraction from the last chromatographic step. In the most preferred embodiment, the non-ionic polyether is poly(ethylene glycol) (PEG).

    摘要: The present invention relates to a process of regenerating a separation matrix, such as a chromatography matrix, comprising adsorption of at least one target molecule by contacting a mobile phase comprising at target molecule(s) with a matrix; removal of unbound material by washing the matrix; elution of target molecule(s) by contacting the matrix with an eluent; reducing regeneration by contacting said matrix with a reducing agent; alkaline regeneration by contacting the matrix with an alkaline solution; and equilibration of the matrix.

    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 immobilized 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 matrix containing the immunoglobulin containing proteins adsorbed thereon; and recovering said immunoglobulin containing proteins by contacting the matrix with an eluent which releases the proteins. The method improves upon previous separation methods in that each of the ligands comprises one or more of a protein A domain (E, D, A, B, C), or protein Z, or a functional variant thereof, with at least one of the monomers having a substitution of the Asparagine or Histidine at the position corresponding to H18 of B domain of Protein A or Protein Z, and wherein the ligand provides an increase in elution pH compared to non-substituted ligand.
