    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 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 C-terminal most proline residue after the third alpha-helix.

    摘要: A method of determining the relative component proportions of at least one each of: a buffer; an acid or a base; a solvent; and optionally a salt, for providing a liquid mixture of pre-defined pH and ionic strength, wherein the relative component proportions are determined using the equation of Debye-Hückel, wherein the ion size parameter a in the Debye-Hückel equation is determined as the weighted mean ion size of all species contributing to the ionic strength of the liquid mixture, and wherein the ionic strength of each species is used as weighting parameter. The present method is also applicable in a method of providing a liquid mixture. Further there is provided a buffer preparation device.
