Abstract
Polyacrylamide gels containing chaotropic agents such as urea as solubilizing agents for protein or nucleic acid separations are rendered stable for prolonged periods of time by the use of certain diacrylyl compounds with tertiary amide groups as cross linking agents. These compounds have the general structure ##STR1## where the R groups are generally saturated hydrocarbon groups and R.sup.4 through R.sup.9 may also be hydrogen. When used as cross linkers, these compounds have the further advantage of preventing urea crystallization at lowered temperatures.
