甲亢病人术后新鲜甲状腺组织经硫酸铵沉淀和两次SephadexG—200凝胶连续过滤后,可获得纯度高的甲状腺球蛋白,用圆盘电泳鉴定,显示三条带,主带为19S,另两条带为27S和12S成分。
Thyroglobulin with high purity was obtained after the fresh thyroid tissue was precipitated by ammonium sulfate and twice by Sephadex G-200 gel after thyroidectomy. The purity of thyroglobulin was identified by disk electrophoresis. The results showed that three bands were detected, the main band was 19S and the other two bands With 27S and 12S ingredients.
