【Abstract】 This paper reports the study on continued separation of transfer factor (TF) and ribonucleic acid (RNA) from the animal spleen tissue with the method of ultro filtration(UF). The result shows that applying the technique to practice can shorten the process of production and reduce the investment in power and equipments.By adopting this method which has been brought forward for the first time, the production has increased considerably. It is more appropriate for industrial production on a large scale than the traditional technique.更多还原
