Peptides which bind to alpha-1 Proteinase inhibitor (AlPI) are disclosed. The peptides have an available AlPI binding domain which may be any of the following preferred sequences: Val Ile Trp Leu Val Arg, Ile Ile Trp Leu Tyr Lys, Arg Tyr Arg Ile Phe Ile, Arg Ala Phe Trp Tyr Ile, Arg Phe Ile Tyr Tyr Thr, Tyr Lys Phe Arg Phe Trp, Leu Ile Val His Arg Trp, Pro Tyr Trp Ile Val Arg, Ala Arg Trp Tyr Ile His, Gln Tyr His Phe Trp Tyr, Arg Leu Trp Arg Tyr Gly, Val Ile Tyr Leu Val Arg, Val Ile Phe Leu Val Arg, Lys Ile Phe Leu Val Arg, Arg Ile Phe Leu Val Arg, His Ile Phe Leu Val Arg, Arg Val Leu Phe Ile Val, or Arg Val Leu Phe Ile His (SEQ ID NOS: 1-8, 10, 11, 15, 36, 37, 45, 46, 47, 61, and 62 respectively). A method of using peptides having these available binding domains in an affinity chromatography process to purify AlPI is described.
