A process for the separation of a fragment antibody from a medium is provided. The process comprises contacting the medium comprising the fragment antibody with a synthetic affinity ligand attached to a support matrix under conditions whereby the fragment antibody binds to the synthetic affinity ligand. The synthetic affinity ligand has the formula (I): wherein Q represent an attachment to a solid support matrix, optionally via a spacer group; A and B are each independently —Y-phenyl or —Y-naphthyl groups substituted with one or more substituents capable of hydrogen bonding, preferably one or more of —OH, —SH or —CO2H groups; each Y independently represents —NR—, —O— or —S—; and each R independently represents H or a C1-4 alkyl group.
