    • 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.
    • 来自各种来源的内皮细胞生长因子(ECG)对肝素具有强烈和特异性的亲和力。 心电图对肝素的强亲合力能够通过以下方式从含有ECG的混合物中除去不想要的杂质:a)使固定化的肝素与混合物接触以形成肝素-ECc复合物; b)从络合物中分离未络合的混合物; 和c)使所述配合物与盐浓度和pH的盐溶液接触,以将ECG与肝素分离。 所得纯化的ECG(或其片段)可用于治疗学和作为细胞培养的添加剂。 纯化的ECG也可用于产生用于治疗和ECG免疫测定中的抗体。
