English to Russian Medical Medical (general)

After incubating at a non-permissive temperature (about 37 C) for a day, the treated cdcl3-l cells are stained with MitoTracker Green (or any suitable mitochondrial mass staining agents) for 20 min in the dark. Plates are read by a fluorescent microplate reader. Since dead cells contain more deteriorated mitochondria which have lost membrane potential, they would show dramatic increases in mitochondria mass staining. The compounds or compositions that improve mitochondrial function and prevent cell death would reduce mitochondrial deterioration, decrease mitochondrial mass signals, and thus are considered as positives. The positives will be further tested for their ability to prolong senescence in yeast and human models.
