The polymer solution from coils shrinking concentration Cs to uniform entangled concentt concentration C+ has been defined as semi-dilute solution. We experimentally investigated the electrophoretic migration behavior of 100 bp deoxyribonucleic acid (DNA) Ladder in hydroxypropyl methyl cellulose (HPMC) concentration ranging from 1.25 g/L to 16.06 g/L. The friction force mobility mu f is used to express the friction force that DNA will encounter in capillary electrophoresis. Our results indicate the division of polymer solution into three regions depending on the relationship of mu f and HPMC concentration and Ferguson plot. Resolutions of 200 bp/300 bp and 700 bp/800 bp show semi-dilute polymer solution suits large fragments and small fragments DNA separation respectively. the results confirm that the current polymer theory is valid under actual CE condition. %K capillary electrophoresis %K deoxyribonucleic acid %K theory of coil shrinking in semi %K dilute polymer solution
