  • Agarose compositions for nucleic acid sequencing
    Patent number: 5455344
    Abstract: A nucleic acid sequencing gel comprising 2 to 10% of a gelling polysaccharide, preferably agarose; a denaturing agent, a non-gelling additive, preferably glycerol, and electrophoretic buffers. This composition is capable of resolving nucleic acid fragments having at least 50 bases and which differ from each other by at least one base.
    Type: Grant
    Filed: September 3, 1993

  • Polysaccharide resolving gels and gel systems for stacking electrophoresis
    Patent number: 5143646
    Abstract: Electrophoretic resolving gel compositions, discontinuous stacking gel systems containing these and other resolving gel compositions, and kits for preparing such gel systems, comprising one or more polysaccharide hydrogels of which agarose is typical wherein at least one of the gels in the resolving gel composition has been derivatized and at least one of the gels in the resolving gel composition has been depolymerized sufficiently to reduce its casting-effective viscosity.
