Multimembrane stack separates similar proteins

Research output: Contribution to specialist publicationArticle


A system to fractionate proteins much closer in size to each other is now available. The system uses a stack of membranes with no gaskets or spacers between them to separate two similar proteins. Membrane rejection of one of the proteins is amplified with each additional membrane until one of the proteins is completely reflected. The protein that passes through the series of membranes can be purified from the filtrate. The membranes can be cleaned in situ and the system can be operated continuously, thus lowering costs.
