日本味素中央研究所柴井博四郎主任研究员在日本农艺化学大会上宣布,他所领导的研究小组发现了一种能抑制癌细胞繁巯,使其恢复到正常细胞状态的人类蛋白质,而且已经研究成功大量合成的方法。可望一种副作用很小的治癌新药不久将问世。这种物质叫做“成红细胞分化因子”(EDF)。它是用最强的致癌物质——霍尔邦尔酯刺激从白血病患者提取的THPI 细胞,而构成的分子量为2万5千的蛋白质。按1毫升培养液5毫微克(1毫微克=1/10亿克)成红细胞分化因子的比例,将成红细胞分化因子放入
At the Japan Agronomic Chemistry Conference, a researcher at Japan’s Ajinomoto Central Research Institute announced that his group has discovered a human protein that inhibits cancer cells from becoming thickened and returning them to their normal cellular state, and has studied Successful synthesis of a large number of ways. It is expected that a new type of cancer medicine with little side effects will soon come out. This substance is called “erythroid differentiation factor” (EDF). It is the strongest carcinogen - Holborn resin stimulated THPI cells extracted from leukemia patients, which constitute the molecular weight of 25,000 proteins. According to the ratio of 1 nanogram (1 nanogram = 1/1 billion gram) of culture medium to red blood cell differentiation factor, erythroid differentiation factor
