| Abstract: | Objective: To study appilication of in situ nick translation labeling(ISNT) technique on apoptotic cells of testis in the rat. Methods: The DNA strand with breaks was elongated in the presence of digoxigenin 11 dUTP by Klenow fragment of polymerase at the nicked sites. The digoxigenin moieties were incorporated into the newly synthesized strand and were visualized with alkaline phosphatase labeled antidigoxigenin antibody. Results: The apoptotic cells were labeled by ISNT in testis. There were 0 3 apoptotic cells in a convoluted seminiferous tubule. Thick of tissue sections was 10um. Conclusion: The technique can be applied to study apoptosis of testis in various physical and pathologic conditions. |
