Talking about centrifugation, one of its applications is determining proteins's molecular weight. However it can be used for separating proteins from mitochondria and nuclei (for example). The two procedures are different, I think also for what concerns machinery and time.
Now, here is my question. My professor gave us a test-yourself exercise and one of the statements is:
'In order to separate proteins using centrifugation, a low rate centrifuge is sufficient.'
Is it true or false? In my opinion it is just a matter of which kind of procedure we are talking about.
