    Magnet for column-free immunomagnetic separation

Overview

The EasySep™ Human Extracellular Vesicle (CD81) Positive Selection Kit isolates highly purified human extracellular vesicles from plasma/serum and cell culture conditioned medium by immunomagnetic positive selection. Extracellular vesicles are labeled with Tetrameric Antibody Complexes recognizing CD81 and magnetic particles. Labeled extracellular vesicles are separated without columns using an EasySep™ magnet. Unwanted biofluid components are simply poured off, while desired extracellular vesicles remain in the tube. Isolated extracellular vesicles are available for downstream applications such as DNA/RNA extraction, Western blot, or mass spectometry.​

Data Figures

Positive isolation of EVs with the CD81 tetraspanin marker from human plasma and MSC-conditioned medium.

Figure 1. Typical Western Blot Analyses of EVs Isolated from Human Plasma and Mesenchymal Stromal Cell (MSC)-Conditioned Medium

The Western blot analyses in the above examples show positive isolation of EVs with the CD81 tetraspanin marker from (A) human plasma and (B) MSC-conditioned medium. Western blots were run under non-reducing conditions.

Figure 2. Tetraspanin Protein Expression and Recovery of EVs Using EasySep™ Human Pan/CD9/CD63/CD81 Extracellular Vesicle Positive Selection Kits

EVs were isolated from plasma using either EasySep™ Human Extracellular Vesicle Positive Selection Kits or differential ultracentrifugation (2 x 70 min, 100,000 xg) and isolated fractions were analyzed by western blot for tetraspanin protein expression.
