ExoView外泌体全面表征试剂盒
外泌体计数、粒径、蛋白表达、蛋白共定位一次完成
检测样本类型
对细胞培养上清、血浆、血清、尿液、脑脊液、唾液等生物样本中的外泌体直接进行分析
捕获抗体种类
anti-CD81, anti-CD9, anti-CD63, 同型IgG对照;可自定义
单次上样体积
35 µl稀释样本
重复检测数目
3复孔
荧光抗体种类
CD9(Blue)/ CD81(Green)/ CD63(Red)
实验原理
① 35 μL外泌体样品滴加在芯片上孵育;
② 预先包被的抗体特异结合外泌体表面蛋白以捕获外泌体;
③ 再使用荧光抗体特异性标记需要表征的标记物;
④ ZH用ExoView R100检测外泌体粒径、计数、蛋白表达(CD9,CD81,CD63等)及共定位。

特异性捕获
芯片上可包被多达6种捕获抗体,特异性捕获含特定蛋白标记物的外泌体。
JD阳性外泌体计数
芯片捕获外泌体后,可通过SP-IRIS技术直接检测样品中外泌体的数量。
单个外泌体蛋白共定位分析
检测每个外泌体的荧光信号并进行统计,可获得荧光共定位信息,用于分析样品中不同表型外泌体的比例(如右图所示)。
无需纯化
使用抗体捕获模式,防止样品中杂质影响结果,可直接检测血液、尿液和细胞培养液中的外泌体,未纯化样品的测量结果与纯化后基本一致(如右图所示)。
粒径分辨率高
高精度SP-IRIS技术,可检测≥50 nm的外泌体,测量结果与电子显微镜检测结果基本一致,并统计生成外泌体的粒径分布结果(如右图所示)。
可检测外泌体内容物
试剂盒配套相应的穿膜剂,可穿透外泌体并对外泌体内容物进行染色并检测,未穿膜时只能检测到跨膜蛋白CD9的荧光信号,穿膜后即可检测到外泌体内容物Syntenin的表达(如右图所示)。
