I'm working with exovesicles and I wonder whether exosomes can be purified using a centrifuge which reaches only 30,000 g with centrifugation about 16 hours, to obtain the same result with ultracentrifugation at 100,000 g for 1 hour.
Hi, I think at 30 000 g, you will have a contaminated yield of exosomes with larger microvesicles. If you are particularly looking at exosomes, it would be a good idea to filter your sample through 0.22um filter to exclude bigger MVs, in case you do not have an access to ultracentrifuge.
