  • 应用: 细胞凋亡-DNA片段化
检测原理
细胞在发生凋亡时,会激活一些特异性的DNA内切酶,这些内切酶会切断核小体间的基因组DNA。使得凋亡细胞的DNA被切割成180~200bp片段,在琼脂糖凝胶上通常以180~200bp的阶梯状迁移。TdT酶(脱氧核糖核酸末端转移酶)将标记的dUTP连接到断裂DNA暴露的3'-OH末端,通过在这些末端添加荧光dUTP的方式来标记晚期凋亡细胞,从而可以通过流式细胞仪进行检测。

Camptothecin-induced apoptosis in HL-60 cells. Test: HL-60 cells were treated with 2.5 μM Camptothecin for 4h. Control: Normal HL-60 cells were not treated with drugs. Negative: HL-60 cells were treated with 2.5 μM camptothecin for 4h without TdT enzyme.

Q1:Can TUNEL assay kit be used for mouse samples?

There is no species limination in TUNEL assay kits.

Q2:Can the One-step TUNEL kit detect a sperm sample?

Yes, it can be used to test sperm samples.

Q3:What is the difference between TUNEL in-situ kit and TUNEL flow cytometry kit?

The main difference lies in the detection methods, for TUNEL in-situ kits, a fluorescence microscope is used for observing the results, as for TUNEL flow ytometry kit, the sample will be detected by a flow cytometer. On the other hand, TUNEL in-situ kit is more suitable for tissue sections and cell slides or smears, while TUNEL flow ytometry kit is more suitable for suspended cells and adherent cells.

Q4:Is there any TUNEL assay kit that can detect apoptosis in erythrocyte?

The detection of TUNEL is based on DNA fragmentation in late stage apoptosis, so it is not avaliable for erythrocyte as there is no nuclei or other organelles containing DNA in erythrocyte.

Q5:What are the reasons that lead to false positives in TUNEL?

Cells with high proliferative or metabolic active may have a break in the DNA strand, both cases may end up with false-positive result. Evaluation of cell morphology may be used if there are doubts about the interpretation of the results.
