I am interested to isolate vesicles from cell culture supernatant . how long and in what way i can preserve this supernatant to isolate vesicles (if i am not isolating vesicles immediately)
Siranjeevi: I assume you want to analyze the content of vesicles after isolation. First of all, it's important to keep the culture media sterile. You may store the media at 4C for a week or so but not much longer, for accumulating a larger volume.
