Abstract:
An improved composition for the preparation by photopolymerization, in the presence of air at a light intensity of about 1000 mW/square centimeter or less, of gels for electrophoresis, wherein the composition comprises:a) an ethylenically unsaturated monomer, containing on average 1.0 or more units of ethylenic unsaturation;b) a crosslinking agent containing on average more than 1.0 units of ethylenic unsaturation, which may be the same as the monomer;c) a solvent, comprising 50% or more of the weight of the solution, andd) a photoinitiator system to polymerize the gel, in which the photoinitiator is not a riboflavin;the improvement comprising selection of a photoinitiator and a concentration thereof which causes photopolymerization of the gel in about one minute or less in the presence of air at a light intensity of about 1000 mW/square centimeter or less.
