    摘要: Methods for separating casein from soluble proteins in a composition. The method includes: adding a phosphate solution to the composition, mixing to form a mixture, freezing the mixture to obtain a frozen mixture, thawing the frozen mixture to obtain casein-containing aggregates in the mixture, and then centrifuging the mixture to obtain a supernatant traction and a casein-precipitate fraction. The supernatant fraction contains the soluble protein, which may be isolated by subjecting the supernatant fraction to a purification process. The method can be applied to purify a recombinant protein from the milk of a transgenic mammal.
