‘Gel Filtration’ of Organic Compounds

Naturevolume 191pages272273 (1961) | Download Citation



FOLLOWING Porath and Flodin's description1 in 1959 of gel filtration as a fractionation method, it has been regularly used in this laboratory for separation of proteins and polysaccharides from sugar cane juice and sugar factory syrups. Unpublished results of the Swedish workers suggested that the method might be extended to the fractionation of substances in a narrow range of quite low molecular weights. Because of the possibilities of the method materials other than cross-linked dextran have been investigated here as alternative media for gel filtration.
