Abstract
Covalently cross-linked, mixed-bed agarose-polyacrylamide matrices for electrophoresis and chromatography are disclosed. The mixed-bed matrices are formed by the copolymerization of a substituted agarose mixture with acrylamide monomers. The disclosed matrices have improved polymerization properties enabling the formation of gels which have higher porosity and elasticity than conventional gels and which are therefore particularly suited to the separation of intermediate size DNA fragments and high molecular mass proteins.
