Fig. 2From: Endoplasmic reticulum stress increases exosome biogenesis and packaging relevant to sperm maturation in response to oxidative stress in obese mice The characteristics of the purified exosomes. A The exosomes observed by transmission electron microscopy (TEM), Bar = 500 nm. B The size of the exosomes detected by NTA. C Identification of the CD9, Flotillin 1, CD63 and TSG101 in the exosome protein by Western blot analyses. The samples loaded in the lane1 and lane2 were exosome protein extracted from the epididymis of normal miceBack to article page
