Abstract: PURPOSE: A glycoprotein having sialic acid is prepared economically by culturing transformed cell with a gene of glycoprotein containing sialic acid in a medium comprising glycoprotein inhibiting sialidase competitively. CONSTITUTION: Protection of a glycoprotein(glycoprotein I), which is Erythropoietin or Chinese Hamster Ovary(CHO), containing sialic acid is achieved by adding commercially other available glycoprotein(glycoprotein II), γ globulin, having sialic acid into medium. The addition of glycoprotein II results in relative decrease of desialiation of expressed glycoprotein. The added glycoprotein has to have properties such as high content of sialic acid, nontoxic to animal cells, easily and commercially available. γ globulin or heat or trypsin treated γ globulin is used to produce glycoprotein. Erythropoietin (EPO) gene transfected CHO cell is cultured in roller bottle and expressed protein is analysed in IEF gel. The activity of EPO with added γ globulin in the culture medium is assayed with EIA. Addition of heat treated (50-60°C for 30 minutes) or 0.2% of trypsin treated (30-90 minutes) gamma globulin at concentration of 1g/L produces active EPO having pI value at 3.5-4.0.

Title: 스프링이 보조된 멀티노즐 과열저감기
IPC: F22G5/12
Filed: 1996-08-22
Abstract: 증기 과열저감기는 증기 라인으로 연장되는 본체를 갖고 증기라인에서 과열량에 반응하여 제어된 가변 수압 공급원에 의해 작동된다.   공급 라인의 압력이 증기 라인의 증기압보다 더 큰 미리 결정된 수준 이상으로 증가되기 때문에, 피스톤은 수압을 증가시키므로서 증기 라인으로 분무된 물의 양이 점차적으로 더 증가하도록 다수의 분무 개구부를 점차적으로 개방하는 보정된 스프링에 대항하여 위로 상승한다.
