PROCEDIMENTO DI ISOLAMENTO E DI RICUPERO DI ORMONI PROTEICI DERIVATI DA TESSUTI PITUITARI

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.
