一般描述

Percoll®是一种用于细胞、病毒和亚细胞颗粒密度梯度离心的经典培养基。Percoll由直径为15-30 nm（在水中为23％ w/w）并涂覆有聚乙烯吡咯烷酮（PVP）的胶体二氧化硅颗粒组成。PVP涂层使产品完全无毒，非常适合与生物材料一起使用。

应用

Percoll®已用于在精子准备中以研究牛胚胎的能量需求。
Percoll由粒径为15-30nm(在水中为23% w/w)的硅胶颗粒组成，这些颗粒被聚乙烯吡咯烷酮(PVP)包覆。 它被用来建立无毒低粘度，低渗透压密度梯度，可用于分离细胞，细胞器和病毒。它已被用来分离 大肠杆菌的内外膜泡。 Percoll在整个梯度过程中都是等渗的，无毒，并且很容易从纯化的材料中去除。
