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 预包被的抗体异结合外泌体表面蛋白以捕获外泌体；
③ 再使用荧光抗体异性标记需要表征的标记物；
④ 后用ExoView R100检测外泌体粒径、计数、蛋白表达（CD9，CD81，CD63等）及共定位。

试剂盒点
异性捕获 芯片上可包被多达6种捕获抗体，异性捕获含定蛋白标记物的外泌体。
|
|
对阳性外泌体计数 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）。
