For optimal resolution of DNA greater than 2 kb in size in standard gel electrophoresis, 5 to 8 V/cm is recommended (the distance in cm refers to the distance between electrodes, therefore this recommended voltage would be 5 to 8 multiplied by the distance between the electrodes in cm).
Para a resolución óptima do ADN maior de 2 kb de tamaño na electroforese en xel estándar, recoméndase de 5 a 8 V/cm (a distancia en cm refírese á distancia entre eléctrodos, polo que esta voltaxe recomendada sería de 5 a 8 multiplicada pola distancia entre os eléctrodos en cm).
