IMPROVED PROCESS FOR PURIFYING GROWTH FACTORS FROM MILK AND PRODUCTS THEREOF

摘要

The invention provides process for purifying RNAses and growth factors from milk or lactoferrin, the process comprising subjecting the milk or lactoferrin to filtration to separate it into a retentate fraction comprising lactoferrin and a permeate fraction comprising growth factors and/or RNAses, wherein prior to and/or during filtration the milk or lactoferrin is subjected to salt treatment such that growth factors and/or RNAses flow into the permeate. The invention also provides RNAses and growth factors obtained from the process of the invention.
