The present invention relates generally to affinity ligands and chemical affinity ligand-matrix conjugates for use as chromatographic adsorbents and methods which utilise the adsorbents in the purification of proteins by affinity chromatography. The affinity ligand-matrix conjugates of the present invention comprise ligands of general formula (I): wherein m represents an integer from 0-2, n represents an integer from 0-6, p represents an integer from 0-4, R
1
represents H or C
1-3
alkyl, R
2
is an optional substituent, and X is the position at which the ligand is immobilized, optionally via a linker.
