Size exclusion chromatography (SEC) separates components of a sample on the basis of their molecular size. Differential exclusion or inclusion of the molecules is achieved via filtration through a gel ...
Exclusion chromatography can be used to separate molecules on the basis of size 1,2. The technique described here, which uses gel filtration to separate high-molecular-weight DNA from smaller ...
