Description

TUNEL Apoptosis Detection Kit for Cryopreserved Tissue Sections (FITC-labeled POD) (Cat. No.L00301) is used for the detection of fragmented DNA in the nucleus during apoptosis. In this modified TUNEL assay kit, biotin-labeled nucleotides bind with the DNA 3'-OH ends using natural or recombinant terminal deoxynucleotidyl transferase (TdT or rTdT). Streptavidin-FITC is then used to bind with biotin-labeled nucleotides, therefore,the fluorescence could be observed by fluorescence microscope. And then the compound of anti-fluorescein antibody conjugated Peroxidase (POD) is bound to these fluorescein labeled nucleotides, which are detected using the peroxidase substrate, hydrogen peroxide, and 3,3’-Diaminobenzidine (DAB) -Solution, a stable chromogen. Using this procedure, apoptotic nuclei are stained dark brown.
