Hi,
To concentrate a protein, what speed should be used in centrifugal filter? Does protein stick to membrane? Some people say that concentrating your protein will lead to aggregation, is it true??
Amicon ultra centrifugal filters of different size used as per requirements . Good on line literature available.
Hi, Is there any way to prove that a protein is membrane anchored/peripheral membrane protein? Any simple trick or any technique will be helpful. Thanks
