专利申请范围:把从哺乳动物分离出来的付甲状腺及其组织培养物或细胞培养物经过干燥、粉碎、脱脂,用水提取,然后用蛋白质沉淀剂(最好是三氯醋酸)处理该水提取溶液,则蛋白质及多肽便从提取的水溶液中除去;然后将这不含蛋白质的提取液进行真空冷冻干燥。如果需要进一步精制,最好经凝胶过滤精制后沉淀活性成份。本专利申请范围就是以上述操作过程为特征的含有新的激素(或激素群)的激素浓缩物或混合物制造方法。发明的详细说明:本发明是关于由付甲状腺制备而得的被称做(Litoralon)的新的激素,以及含有这种至今尚未清楚的激素的浓缩物或混合物的制造方法。
Patent application: The thyroid and its tissue cultures or cell cultures isolated from mammals are dried, pulverized, degreased and extracted with water, and the aqueous extract solution is then treated with a protein precipitating agent, preferably trichloroacetic acid , The protein and polypeptide are removed from the extracted aqueous solution; and the protein-free extract is then vacuum freeze-dried. If further purification is required, the active ingredient is preferably precipitated by gel filtration. The scope of this patent application is a method of making hormone concentrates or mixtures containing new hormones (or hormones) characterized by the above described procedures. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to novel hormones called Litoralon prepared from thyrocytes and to processes for the manufacture of concentrates or mixtures containing such hitherto unknown hormones.
