- 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,从而可以通过荧光显微镜进行检测。 |

Q1:流式抗体实验结果的数据不满意/ Annexin V数据不会分析,能帮我分析下吗?
对于使用我司产品的客户,我们提供免费数据分析服务。您可以添加我们流式技术支持的企业微信,并将FCS格式原始数据、细胞样本(具体什么样本、如何处理)、实验分组(空白管、单染管、全染管、每个样本染色了哪些抗体)、流式操作步骤(细胞悬液体积、细胞个数,抗体用量、染色时间和温度)等信息发送我们技术支持同事。
Q2:含有抗荧光淬灭的封闭剂(含DAPI)可以用来封片吗?
可以用来封片,如果用的话就不用我们试剂盒里面自带的DAPI染料,但是由于DAPI孵育后没有清洗,所以会造成较高的背景。
Q3:细菌样本能否用Tunel、Annexin V检测?
老师您好,我们的验证都是在哺乳动物细胞上进行的,细菌的细胞膜结构和哺乳动物细胞膜结构存在差异,这些产品不一定能够适用,建议老师查询文献或者进行预实验来确认。
