Abstract:Artículo de publicación ISIAqueous two-phase systems (ATPS) that are formed by mixing a polymer (usually polyethylene glycol,
PEG) and a salt (e.g. phosphate, sulphate or citrate) or two polymers, and water can be effectively used
for the separation and purification of proteins. The partitioning between both phases is dependent on the
surface properties of the proteins and on the composition of the two phase system as has been recently
reviewed by Asenjo and Andrews . This paper analyses and reviews som…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
