油酸钠层状液晶体系的聚合

将十六烷增溶于油酸钠／水体系层状液晶的油层,共聚单体二乙烯基乙二醇增溶于油酸钠／水体系层状液晶的两亲层,将共聚限制在同一两亲层内油酸钠的双键与共聚单体之间进行。得到了具有层状结构,并具有较好表面活性的共聚物。

中压液相色谱纯化牛血红细胞超氧化物歧化酶

A rapid and effective purification of superoxide dismutase from bovine erythrocytes by MPLC is repoted.After bovine erythrocytes were treated with chloroform-ethanol to remove hemoglobin,acetone was used toremove contaminant proteins.Then highly purified Cu-Zn SOD(the specific activity was 10 000～15 000U/mg pr.)was obtained by twice DEAE-Sepharose chromatography using different eluting procedures.SDS-PAGE of the Cu-Zn SOD purified as above revealed one band. The molecular weight was 1 5 000～17 000.
