摘要
本文研究了从牛初乳中用中空纤维超滤膜分离纯化牛初乳类胰岛素生长因子(IGF-I与IGF-Ⅱ),并利用放射免疫测定法(RIA)测定IGF-I与IGF-Ⅱ的浓度。结果表明:在碱性条件下超滤有利于提高类胰岛素生长因子的回收量。
The purification of bovine colostrums insulin-like growth factors with the dialysis and polyacrylonitrile hollow fiber ultra-filtration membrane was studied. The density of IGF-I and IGF-Ⅱ could be assayed through radio-immunoassay (RIA). The results showed that the recovery of insulin-like growth factors(IGFs) is optimal on alkaline diafiltration.
