Annexin V-FITC/7-AAD Apoptosis Kit
中文名称:Annexin V-FITC / 7-AAD细胞凋亡检测试剂盒
Price:
- 应用: 细胞凋亡-Annexin V
检测原理 | Annexin V是一种钙离子依赖性磷脂结合蛋白,与磷脂酰丝氨酸PS有高度亲和力,可通过细胞外侧暴露的PS与凋亡早期细胞胞膜结合,将Annexin V标记荧光染料,利用流式细胞仪检测细胞凋亡。
细胞核染料(PI,DAPI,7-AAD)可与双链DNA特异性结合,并产生强烈的荧光,正常情况下无法透过细胞膜。由于凋亡晚期或坏死细胞膜丧失完整性,细胞核染料(DAPI、PI、7-AAD)可进入细胞内对DNA进行染色,与Annexin V搭配使用,可区分处于不同凋亡时期的细胞。 |

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。
