- Figure 3 Characterization of EVs obtained by FPLC in comparison to EVs isolated by the DC protocol. EVs were prepared as described for the specific method. One sample from HEK293 cells expressing polyhistidine-tagged FRalpha was split into two halves to compare the expression of protein markers. For each step and method 1 ug total protein was loaded onto a gel. The blots were probed for EV-enriched proteins like FRalpha, flotillin and Alix. Additionally, the reduction of intra- and extracellular contaminations was investigated with the proteins TOM20 and the stably expressed PTPS. For this analysis we considered also the intermediate centrifugation steps of the DC protocol. Peak II (PII) of the two-step FPLC combining SEC and IMAC shows the strongest recovery of EV markers and reduction in EV-negative ones.
