However, when charges are not all uniform then, the electrical field generated by the electrophoresis procedure will affect the species that have different charges and therefore will attract the species according to their charges being the opposite.
Porén, cando as cargas non son todas uniformes entón, o campo eléctrico xerado polo procedemento de electroforese afectará ás especies que teñan diferentes cargas e, por tanto, atraerá as especies de acordo coas súas cargas opostas.
