the resulting particles were harvested , and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis for membrane protein content and by enzymic analysis to detect the presence or absence of the exofacial enzyme acetylcholinesterase ( ace ) , the cytosol facing enzyme glyceraldehyde phosphate dehydrogenase ( gapd ) , and the integral protein adenosine triphosphatases ( atpases ) .
