Coomassie stained gel of proteins isolated from exosomal fractions derived from primary microglia. Primary microglia (2500000 cells) were treated with or without Wnt3a (10 nM) for 8 hours in SFM. Cell culture medium was collected, centrifuged at 10000xg for 10 minutes, concentrated using 3kDa centrifugal devices and exosomes were isolated at 100000xg. Proteins were separated by SDS-PAGE and visualised using coomassie blue.
