Tunel aortalno-lewokomorowy — rzadka przyczyna szmeru skurczowo-rozkurczowego

TUNEL vision spots apoptotic cells

By the early 1990s, scientists knew that programmed cell death, or apoptosis, was important for tissue development and homeostasis as well as for cancer progression. Because apoptotic cells activate nucleases to cleave their chromatin, cell death could be followed in vitro by extracting DNA from a population of tissue culture cells and running it out on an agarose gel to look for a characterist...

TUNEL assay. An overview of techniques.

Fragmentation of sperm DNA using the TUNEL method.

OBJECTIVES To establish the validity of the TUNEL assay in determining sperm DNA fragmentation, the relationship between the degree of fragmentation and the seminal parameters and the sample needed to conduct the test. MATERIAL AND METHODS We used semen samples from healthy fertile men (n=33), patients who consulted for infertility with a prescription for the TUNEL assay (n=77) and patients w...

TUNEL-antibody double-labeling method for Drosophila embryos.

The terminal deoxynucleotide transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) method for monitoring targeted cell ablation is based on the in situ labeling of DNA fragmentation sites in nuclei of intact fixed cells. Unlike other methods of detecting dying cells, the use of fixed material allows antigen expression to be monitored at the same time that apoptosis is confirmed in the targe...
