外泌体提取试剂(微球法)

原理

捕获法提取外泌体是基于磷脂酰丝氨酸(PS)的可逆结合洗脱,上海乐赛生物采用与外泌体高亲和力的微球粒子的纯化方式。样品在结合缓冲液(EV-CB)的作用下外泌体特异的吸附在微球/磁珠的表面,而其他非磷脂蛋白质等杂质则不被吸附而去除。吸附了外泌体的微球/磁珠经洗液洗涤去除蛋白质和其他杂质,最后,纯化的外泌体被洗脱液EB洗脱。

产品特点
►快速提取:全过程缩短至1小时以内(微球法)
►操作便捷:只需要简单离心(或磁吸)/混合操作
►全样本覆盖:血清/血浆,尿液,细胞培养上清
►通量适中:适合中等样本量外泌体快速纯化,磁珠法可实现高通量自动化

鉴定
不同样本来源外泌体采用电镜、NTA和CSFE染色后FACS检测
1.使用乐赛生物外泌体提取试剂提取EVs透射电镜检测结果:


细胞上清外泌体            人尿液外泌体               牛奶外泌体

2.使用乐赛生物外泌体提取试剂盒提取EVs的CSFE染色流式细胞仪结果:



竞争产品
MagCapture™ Exosome Isolation Kit PS 299-77603 WAKO

竞争优势
采用磷脂酰丝氨酸(PS)高亲和力结合磁微粒材料,可以直接与PS可逆结合,洗脱得到纯 度较高的外泌体,不含螯合剂等可能影响后续实验的试剂。WAKO 采用特有的Tim4标记磁微粒通过钙离子桥间接结合PS,成本较高,外泌体结合易脱落,操作步骤繁琐,洗脱后外泌体中含有大量螯合剂,影响外泌体活性及后续实验。
