<b>Visualizing mitochondria in mammalian cells using mCherry or AcGFP1 fluorescent proteins.</b> HCT116 cells and Hela cells were transduced using Cat. Nos. 0024VCT and 0017VCT respectively. The lentivirus vectors express a fusion protein consisting of a fluorescent protein tagged with the targeting sequence from subunit VIII of cytochrome c oxidase that targets mitochondria.
