FREMGANGSMAATE FOR ISOLERING OG UTVINNING AV PROTEINHORMONER SOM STAMMER FRA HUMANT HYPOFYSEVEV

摘要

Protein hormones are fractionated and isolated from extracts of pituitary glands or tissues. Increased yield and purity of the growth hormone is obtained by using controlled amounts of polyethylene glycol as precipitating agent at pH = 4-6, preferably 4.5-5.0 and separating the precipitated fractions.
