Exo-spin ™技术结合了沉淀法和SEC方法,可进行外泌体的分离和浓缩。产品有不同的配置组合,适用于不同样本类型。
尺寸排除色谱法(Size Exclusion Chromatography,SEC)原理介绍
SEC是一种根据颗粒大小分离溶液中颗粒的方法。色谱柱采用稳定的多孔的凝胶颗粒填充。当将含有外泌体的溶液加入到 SEC 色谱柱中时,较小的颗粒将被捕获在孔中,而较大的分子则不会进入孔中并被先洗脱。因此,不同阶段的洗脱部分将包含不同大小的分子,首先是较大的外泌体颗粒,其次是较小的蛋白质和脂质颗粒
SEC方法是获得高纯度样品的理想方法,可以将外泌体与其他非外泌体成分分开,同时适用不同体积的起始样本。
Exo-spin ™技术特点
Exo-spin ™技术结合了沉淀法和SEC方法,可进行外泌体的分离和浓缩,从而实现外泌体的高特异性和高回收率。Exo-spin ™有不同的配置组合,货号分别为EX01,EX02,EX03,EX04和EX05;专为不同样本类型(上清、血清、血浆、尿液、唾液、脑脊液等)和下游应用设计和优化。
Exo-spin ™选购指南
针对不同的样本,Exo-spin™为您提供最佳提取方案:
注:常规基本操作流程需要沉淀,然后使用SEC色谱柱进一步纯化。但如果外泌体浓度较高,可省略沉淀步骤。沉淀剂会影响质谱分析,因此样本处理应避免使用沉淀剂,可直接使用纯化管柱。
