Medium for electrophoresis.

摘要

A medium for electrophoresis suitably employable for analysis of biopolymers such as proteins, as well as for determination of base sequence of DNA, RNA, their fragments, and their derivatives, which comprises an aqueous polyacrylamide gel formed by crosslinking polymerization of an acrylamide compound and a crosslinking agent having at least three reactive groups in the presence of water. The medium for electrophoresis may contain a water-soluble polymer and agarose. The medium may contain a modifier such as an anionic surfactant, formamide or urea. A medium for electrophoresis which comprises a plastic material support and a medium layer for electrophoresis superposed thereon, said layer comprising an aqueous polyacrylamide gel formed by crosslinking polymerization of an acrylamide compound and a crosslinking agent having at least three reactive groups in the presence of water is also disclosed.
