Polyclonal Immunoglobulin (Ig) G from patients with rheumatoid arthritis (RA) and healthy subjects hydrolyzed carbobenzoxy-Val-Gly-Arg p-nitroanilide and D-Pro-Phe-Arg p-nitroanilide. RA IgG exhibited higher activity against the former substrate, but not the latter. On the other hand, RA IgG showed reduced

For the simple purification of porcine pancreas kallikrein, various affinity chromatographies using L-prolyl-L-phenylalanyl-L-arginine (Pro-Phe-Arg-OH), tosyl-L-arginine (Tos-Arg-OH) and acetyl-L-phenylalanyl-L-arginine (Ac-Phe-Arg-OH) as ligands were examined. The purification was performed as follows using the extract from acetone powder of porcine pancreas as starting
