MEDIUM FOR ELECTROPHORESIS

摘要

A medium and a method for electrophoresis is disclosed, wherein the medium comprises (a) a polytetrafluoroethylene (PTFE) fibril matrix, and (b) particulate, electrically mobile ions, and sufficient liquid in the interstitial spaces of said matrix to allow for ion transport, the ratio of said particulate to PTFE being in the range of 99:1 to 4:1 by weight, and said ions being present in said liquid in an amount to provide a solution of concentration in the range of 1 to 1000 millimolar, and wherein almost all of said particulate are separate one from another and are isolated in cages or cage-like structures of PTFE microfibers.
