1. A method for producing an output mixture of two or more different antibodies having a difference in their amino acid sequences, which difference enables separation of the antibodies by chromatography, wherein the difference in the amino acid sequence of said two or more different antibodies results in a difference in (i) the charge properties of the two or more antibodies so that the two or more antibodies interact differently with a chromatography resin, (ii) the hydrophobic properties of the two or more antibodies so that the two or more antibodies interact differently with a chromatography resin, or (iii) affinity for a chromatography resin, and wherein
the two or more different antibodies are present in said output mixture at, or essentially at, a desired or predetermined concentration ratio; and
the method comprises the steps of:
(a) providing an input mixture wherein the two or more different antibodies are not present at, or essentially at, the desired or predetermined concentration ratio;
(b) separating the two or more antibodies by said chromatography; and
(c) recovering the two or more antibodies in the amounts required to provide the output mixture.
