Popis: | Immuno-flow cytometry was tested as a tool to estimate the cellular concentration of mitochondrial proteins in cultured cells, using cytochrome c oxidase as a model enzyme. Cells labelled with antibodies against cytochrome c oxidase, in which the amount of the enzyme was reduced by various extents, showed a linear relationship between the size of the signal obtained by immuno-flow cytometry and the amount of the enzyme. The determination by immuno-flow cytometry resulted in data comparable to the results obtained by immunoprecipitation and activity measurement. Since immuno-flow cytometry requires only limited numbers of cells, the method could especially be of value for diagnostic purposes. This is illustrated by the results obtained by comparing activity measurements and immuno-flow cytometry in the initial screening of cell lines derived from patients with deficiencies in the activity of cytochrome c oxidase. |
