Fig. 1From: Transcriptome analysis of cervical cancer exosomes and detection of HPVE6*I transcripts in exosomal RNACharacterization of exosomes derived from cervical cancer cell lines. A Morphometric measurement of cervical cancer exosomes using transmission electron microscopy. Exosomes from indicated cervical cancer cell lines were isolated from culture conditioned medium and prepared for evaluation as described in methods. B Immunoblotting for exosome-specific markers. Exosomal lysates (50 μg/lane) were resolved on SDS-PAGE, electrotransferred and immunoblotted for Flotillin 2, HSP70, and AlixBack to article page
