1Enzymatic activity and chromatographic characteristics of the cell membrane immobilized on silica surface显示文摘A new cell membrane preparation, silica carrier cell membrane (CCM), has been presented, in which cell membrane was immobilized on silica which acted as carrier by the adsorption. The surface characteristics of the silica CCM have been tested by a scanning electron microscope and surface energy spectrometer. Comparison has been made of the changeable rule of enzymatic activity of rabbit red cell membrane in three states: the silica CCM, the suspension and the precipitation cell membranes, with temperature and time. The result showed that the silica CCM still keeps the same enzymatic activity as the other two states of cell membranes. The interactions between calcium antagonists and rabbit red and cardiac muscle cell membranes, and the stereoscopic interactions between dihydropridines and rabbit cerebellar cell membrane have been investigated by the chromatographic system of the silica CCM as a stationary phase. From the foregoing results, the chromatographic parameters obtained from the system wouldLangchong He Guangde Yang Xindu Geng 1999Chinese Science Bulletin1999,44,9:58
