Exosome分离及Exosomal RNA( 含miRNA) 的纯化

 
 

exoEasy Maxi Kit

从血浆、血清、细胞培养上清及其他生物体液中分离完整的 exosome 及其他细胞外囊泡
• 可在25分钟内纯化获得exosome及其他细胞外囊泡
• 离心柱纯化流程,可平行处理多个样本
• 可处理大体积的样本(4 ml 血浆或血清,或 32 ml 细胞 培养上清),灵敏检测低丰度转录本。

   

 

 

exoRNeasy Maxi/Midi Kit

采用亲和性膜离心柱,可从 exosomes 和来自血清、血浆、细胞培养上清液或尿液的其他细胞外微泡中高效分离 RNA。 Maxi 规格的分离柱可处理多达 4 ml 血清 / 血浆、16 ml 尿液或 32 ml 细胞培养上清液,因此能够可靠检测低丰度 RNA。 该试剂盒能够快速、便利的获得结果,十分适用于敏感的下游应用。
exoRNeasy Maxi/Midi Kit 借助于全新的实验流程升级及尿液抑制去除剂 Reagent UI (cat. no. 77900),实现了对尿液这种 复杂样本的全面兼容。在短短的 1 小时实验流程内,不仅能够快速特异性的从大体积起始样本中分离高质量的外泌体或其 他微小囊泡体,也能同时更好的获取可以适合于下游多种检测方法的无抑制剂高纯度 RNA,并能够把长链 RNA 和短链的 RNA 分离开。

 

   

 

     
  Intact vesicles are eluted from the exoEasy membrane with higher purity compared with ultracentrifugation.

Scanning electron microscopy (SEM; 20,000x magnification) was performed on a solubilized pellet from ultracentrifugation of pre-filtered (0.8 µm) plasma compared to an exoEasy eluate. Both preparations contain vesicle-shaped structures with an expected size range from 50–200 nm (white arrows; scale bar 200 nm). The preparation from ultracentrifugation also includes many smaller, unidentified structures that do not match the expected shape and size of extracellular vesicles.







  Characterization of extracellular vesicles isolated using the exoEasy Maxi Kit by Nanoparticle Tracking Analysis (NTA).

(A) HeLa cells were maintained in serum-free medium for 48 h before harvesting culture supernatants. The exoEasy Maxi Kit was used to isolate EVs from 2 ml of supernatant that had been pre-filtered using a 0.8 µm filter. EVs were diluted 1:100 and characterized using the Nanosight NS300 instrument (Malvern, UK). (B) EVs were also isolated from 1 ml of EDTA plasma (measured at 1:200). Mean particle diameters were reported as 212 nm and 214 nm, respectively, which is within the expected range for a mixed population of exosomes and other extracellular vesicles. Red outline indicates variation between 5 repeat measurements.
