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.
