Claim Text:
1. A method of obtaining a product enriched for angiogenin from a milk sample, said method comprising: (a) contacting the milk sample with an anti-angiogenin antibody, such that angiogenin present in the milk sample interacts with the antibody to form an angiogenin-antibody complex; (b) separating the complex from the milk sample; (c) releasing angiogenin from the antibody in the complex; and (d) collecting the angiogenin from step (c) thereby obtaining a product enriched for angiogenin; in which the milk sample is heated to over 70° C. for at least one minute prior to step (a) to reduce the amount of lactoperoxidase and other proteins that denature at lower temperatures than angiogenin in the sample.
