Abstract

An improved electrophoresis apparatus for nucleic acid fragments in which nucleic acid fragments are separated in the order of their molecular weight in an electrophoresis cell using an electrophoretic gel for determining the base sequence of a nucleic acid, the improvement comprising a nucleic acid fragment specimen supply section for supplying the nucleic acid fragments to the electrophoresis cell, disposed thereover a molecular sieving membrane having a predetermined degree of molecular permeability for separating to remove those high molecular weight ingredients in the nucleic acid fragment specimen other than the fragments intended to be analyzed electrophoretically.
