Area of Science:

  • Cell Biology
  • Biochemistry

Background:

  • Apoptosis analysis is crucial for both basic research and clinical investigations.
  • Accurate detection of apoptotic cells is essential for understanding various biological processes and diseases.

Purpose of the Study:

  • To provide a concise overview of the most frequently employed methods for detecting apoptotic cells.
  • To discuss the distinct features and advantages of each method.

Main Methods:

  • Morphological study of cells.
  • Analysis of DNA degradation patterns.
  • DNA end-labeling techniques (e.g., TUNEL assay).
  • Flow cytometric analysis.
  • Nuclease assays.

Main Results:
