Detecting Apoptosis with TUNEL Staining
Description
TUNEL staining helps detect apoptotic cells by marking fragmented DNA. Apoptosis is a form of programmed cell death, and one of its key signs is nuclear DNA fragmentation by nucleases. These enzymes are activated by caspases, the proteins that carry out the cell death program.

Transcript
The TUNEL assay is most commonly used to detect cells undergoing apoptosis, which is a form of programmed cell death. Apoptosis is an important biological process during development, and for maintaining tissue homeostasis. TUNEL staining allows for visualization and quantification of apoptotic cells. This helps scientists test...
