title: Affinity chromatography of the phosphatidylcholine exchange protein from bovine liver.
abstract: Affinity chromatography has been used to purify the phosphatidylcholine exchange protein from bovine liver. The affinity resin consisted of 1-acyl-2-(9-carboxy)nonyl-glycero-3-phosphocholine linked to AH-Sepharose 4 B via the carboxyl group. Application of a crude exchange protein fraction to the affinity column resulted in a complete adsorption of the phosphatidylcholine exchange protein. The exchange protein eluted with a buffer containing 0.15% sodium deoxycholate. The most active fraction was 130-fold purified and accounted for 62% of the activity.
