Fig. 1From: Exosomal tRF-Leu-AAG-001 derived from mast cell as a potential non-invasive diagnostic biomarker for endometriosisIdentification of isolated EVs in tissues and leucorrhea. A The morphology of EVs was analyzed by TEM (< 200 nm). B The diameter distribution of EVs was analyzed with a nanoparticle analyzer. C Western blot analysis of exosomal marker protein Flotillion 1, HSP70, CD63, Calnexin. Western blot results showed HSP70, flotillion 1 and CD63, three well-known protein markers, were enriched in exosomes from ectopic tissue and leucorrhea but were undetectable in the cells.While the exosomal negative marker protein, calnexin, was expressed in cellsBack to article page
