采用“国际标准化系统”制备人白细胞干扰素,要用人的新鲜静脉血(或血库贮存的血),并需从中提取出生长活性良好的白细胞,供作诱生干扰素。这样不仅来源困难,价格昂贵,且操作手续较繁,易影响干扰素的产量。为了克服这些缺点,我们采用中国医学科学院 The use of “international standardization system” for the preparation of human leukocyte interferon, the use of fresh human venous blood (or blood stored in the blood bank), and the need to extract from good growth and activity of white blood cells for the production of interferon. This is not only difficult to source, expensive, and frequent procedures, easy to affect the yield of interferon. In order to overcome these shortcomings, we use the Chinese Academy of Medical Sciences
