Figure 1: MalaEx visualized by TEM analyses.

(A,B) MalaEx were isolated by ultracentrifugation followed by sucrose gradient centrifugation. Fractions ranging in density from 1.11–1.20 g/ml were pooled and analysed by TEM. Images show exosomes that derive from M. sympodialis which have been cultured at pH 5.5 (A) or at pH 6.1 (B). Scale bar indicates 200 nm.
