Concentrated porcine serum with ultrafiltration 30KDa was purified with DEAF-Sephacel column chromatography. Buffer solution with pH 7 to 9 and buffer concentration with 0.01M to 0.05M, and NaCl gradient with 0M∼0.5M, 0M∼0.8M and 0M∼1.0M were used respectively for chromatographic purification. Optimal conditions were at pH 8.0, buffer conc. 0.03M and salt conc, 0M∼0.5M with immunoprotein concentration 82% and production yield 43%. Purified immunoprotein was identified in the molecular weight 50KDa and 15KDa by electrophoresis.
