DMPC单分子层膜及细胞色素C氧化酶重组脂质体表面的扫描隧道显微镜观察 %A 曾科 %A 林克椿 %A 姚骏恩 %J 生物物理学报 %D 1991 %I %X We have employed a SSX-1 STM to determine the structural properties of a) DMPC monolayer supported on graphite in native environment and b) CL/DPPC liposomes reconstituted with cytochrome c oxidase, coating with a thin Au film afetr air-drying. Images of DMPC monolayer show long range positional as well as or-ientational order and individual headgroups are resolved. Images of liposomes re constituted with cyt. c oxidase show the enzyme molecules exist in membrane in "dimer" and the fine structure of enzyme are also resolved. The results indicate that STM has a great potential in membrane research. %K 单分子层膜 %K 细胞色素 %K 氧化酶 %K STM %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=90BA3D13E7F3BC869AC96FB3DA594E3FE34FBF7B8BC0E591&jid=E0C9D9BBED813D6674AC13E942EAC86D&aid=5E86E445AE6962DC13813ADAD27EB8BB&yid=116CB34717B0B183&vid=DF92D298D3FF1E6E&iid=E158A972A605785F&sid=DA4893B5F9885621&eid=03436AC72A659ACA&journal_id=1000-6737&journal_name=生物物理学报&referenced_num=0&reference_num=1
