Background: The TUNEL In Situ Apoptosis Kit (HRP-DAB Method) has high sensitivity and easy operation. This kit is suitable for in situ apoptosis detection of tissue samples (paraffin sections, frozen sections) and cell samples (cell smears, slides), and the detection results can be observed by optical microscope.
Principle of the Assay: When cells undergo apoptosis, specific DNA endonucleases will be activated, cutting the genomic DNA between the nucleosomes. The exposed 3'-OH of the broken DNA can be catalyzed by Terminal Deoxynucleotidyl Transferase (TdT) with biotinlabeled dUTP, horseradish peroxidase (HRP)-labeled Streptavidin (Streptavidin-HRP) can be combined with biotin. So apoptotic cells can be observed by DAB reaction with optical microscope.
