Resumen:
 Peptide Ala-Pro-Ala-Arg (APAR) was selected from the screening of a tetrapeptide combinatorial synthetic library as the ligand for affinity purification of an anti-Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) monoclonal antibody (Mab) developed in mouse ascitis. The affinity chromatographic matrix obtained by attachment of APAR to agarose, having a peptide density of 0.5 µmol/ml, showed a maximum capacity of 9.1 mg Mab/ml and a dynamic capacity of 3.9 mg Mab/ml. 95 % yield of electrophoretically pure anti-GM-CSF was obtained in a single step.
