产品概述
TUNEL Assay Kit - FITC ab66108 provides complete components, including positive and negative control cells, for detecting DNA fragmentation by fluorescence microscopy or flow cytometry.
The TUNEL assay is used to detect DNA fragmentation, such as in apoptosis. It uses terminal deoxynucleotidyl transferase (TdT) to catalyze the incorporation of deoxynucleotides at the free 3'-hydroxyl ends of fragmented DNA. The deoxynucleotides are then labeled in a variety of ways for detection of the degree of DNA fragmentation.
The TUNEL assay protocol in this kit uses the deoxynucleotide fluorescein-12-dUTP. DNA which has been labeled with fluorescein can then be analyzed by flow cytometry or fluoresence microscopy with Ex/Em 488/520 nm. Propidium iodide is also included in this kit as a counterstain with Ex/Em 488/623 nm.
TUNEL assay protocol summary:
- fix cells with formaldehyde for 15 min on ice
- wash with PBS
- add ice-cold 70% ethanol and incubate for 30 min
- pellet cells and resuspend in wash buffer and wash again
- pellet cells and resuspend in staining solution and incubate for 60 min at 37ºC
- add rinse buffer, pellet cells and discard supernatant, and rinse again
- resuspend cells in propidium iodide/RNAse A solution and incubate for 30 min at room temp
- analyze with flow cytometer or fluoresence microscope -
说明
This product is manufactured by BioVision, an Abcam company and was previously called K402 ApoDIRECT DNA Fragmentation Assay Kit. K402-50 is the same size as the 50 test size of ab66108.
This kit is FITC-labeled (Ex/Em = 495/519nm). It was previously called TUNEL Assay Kit - In situ Direct DNA Fragmentation.
To use BrdU-Red (Ex/Em = 488/576nm) as a label, we recommend TUNEL Assay Kit - BrdU-Red (ab66110).
For chromogenic TUNEL staining, we recommend TUNEL Assay Kit - HRP-DAB ab206386.
Find out more about the TUNEL method in the TUNEL staining / TUNEL assay guide.

Voloboueva et al used TUNEL assay ab66108 to examine the effect of miR-210 inhibition on mitochondrial function and protection against apoptosis.
The reduced number of TUNEL+ve green cells in panel F indicates that the inhibition of miR-210 reduces the degree of apoptosis in cells treated with media preconditioned (CM) by proinflammatory activated microglia.
Green is TUNEL staining. Red is immunostaining of DCX protein. Representative images are shown.
