By incorporating on-chip multiplication gain, the electron multiplying CCD achieves, in an all solid-state sensor, the single-photon detection sensitivity typical of intensified or electron-bombarded CCDs at much lower cost and without compromising the quantum efficiency and resolution characteristics of the conventional CCD structure.
The number of mitochondria present in a cell depends upon the metabolic requirements of that cell, and may range from a single large mitochondrion to thousands of the organelles. In the digital videos presented in this section, normal Gray fox lung fibroblast cells (FoLu line) are expressing monomeric green fluorescent protein (mEGFP) fused to the mitochondrial targeting signal from subunit VIII of human cytochrome C oxidase.
