Abstract RU 2185180 C2

FIELD: medicine. SUBSTANCE: method involves precipitating follicular fluid and the precipitate is lyophilized. Follicular fluid of kettle animals is used as raw material cooled and treated with centrifuging at 1000 rpm before subjecting it to precipitation during 18-25 min. Admixture precipitation is carried out with cooled acetone added to follicular fluid in the volume portion proportion of 2 fro follicular fluid and 3 for acetone. The suspension is hold and centrifuged at 1000 rpm during 28-35 min with precipitate being removed and lyophilized. EFFECT: high degree of protein purity under industrial production conditions. 2 cl
