Amebae have an Hsp60-associated, mitochondrion-derived organelle (crypton). In this study, the crypton was stained with multiple DNA-binding fluorochromes and a monoclonal anti-double-stranded DNA antibody. Transmission microscopy of partially purified cryptons revealed organelles bound by a double membrane.
