Comparing the effects of PBS and trehalose pulse media on human serum exosome size. After storage at −80°C, exosomes isolated from pooled human serum (Innovative Research Inc.) were subjected to electroporation in the presence of PBS or trehalose PBS pulse media at 4°C at selected electric field strengths. Exosome size was measured by DLS (n = 10 measurements; error bars = s.d.) Best fit dotted lines denote linear regression analyses indicated by R2 values. Significant differences between PBS and trehalose pulse media at selected electric field strengths are denoted by p values; p values < 0.05 were considered significant.
