  • Crosslinked polyacrylamide gels with high monomer: crosslinker ratios
    Patent number: 5700365
    Abstract: Improved polyacrylamide-type gels utilizing diacrylyl tertiary amide crosslinkers are disclosed having relatively high monomer:crosslinker ratios in comparison to conventional polyacrylamide gels. The resulting gels have pore structures chemically and physically different from conventional polyacrylamide gels and, when prepared in the optimal monomer:crosslinker ratio, provide superior resolution and structural characteristics over the conventional polyacrylamide gels.
