  • Patent number: 5235042
    Abstract: Endothelial cell growth factor (ECG) from various sources possesses a strong and specific affinity for heparin. This strong affinity of ECG for heparin enables removal of undesired impurities from a mixture comprising ECG by: a) contacting immobilized heparin with the mixture to form a heparin-ECG complex; b) separating uncomplexed mixture from the complex; and c) contacting the complex with a salt solution of a salt concentration and pH effective to separate the ECG from the heparin. The resulting purified ECG (or fragment thereof) is useful in therapeutics and as an additive for cell culturing. The purified ECG is also useful to raise antibodies that are used in therapeutics and in ECG immunoassays.
