Our lab routinely collect exosomes/Evs from primary rat astrocytes. Using serum-free medium (SFM), incubating for 24 hours, and collecting by serial centrifugation/ultracentrifugation. But some people argued that it's better to use medium with EV-free serum rather than SFM.
Thank you very much. As what you respond, we consider that if we use SFM for primary cells, wthere the cells could survival? 24h or less? Later, I will try to compare SFM and EV-free serum.
Additionally, I want to collect the EVs through Life KIT, which did you think?
And, how much cell supernatant with how many cells did you use for collecting?
Thanks again.
