Abstract: 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.

Key words: bovine colostrums, insulin-like growth factors(IGFs), ultra-filtration, purification
