Fig 7. Zeta potential measurements for exosomes isolated from the different techniques and serum volumes.

Using the ZetaView instrument, the zeta potential (mV) was measured for the exosomes isolated with miRCURY (blue), ExoQuick (green), TEIR (red), and UC (yellow) from 5 ml, 1 ml, 500 μl, 250 μl, and 100 μl of human serum. The data in this graph are the mean values of the zeta potential ± SEM (n = 3)
