Abstract
Size-exclusion chromatography (SEC) of DNAs was investigated with stai nless steel columns (6 mml.D. x 250 mm) packed with macroporous spheri cal gels prepared from glucomannan. High molecular weight DNAs (>15kb) were eluted following size-exclusion theory from the columns packed w ith large gels (>130 mum). However, the smaller gels resulted in the l arger elution times for those DNAs. The particle size as well as the p ore size of the packing material were found to be important factors fo r chromatographic separation of high molecular weight DNAs.
