Ready-to-use, gas-stabilized ready-to-use acrylamide solutions with different concentrations and ratios of acrylamide to bisacrylamide. The ROTIPHORESE ® gel solutions are very easy to use and enable reproducible and high-resolution gel electrophoresis. Directions for use ROTIPHORESE ® gel solutions can be used for protein and nucleic acid separation in PAGE gels. The high-purity solutions can be combined with any buffer system. During sequencing, they facilitate the preparation of sequencing gels of consistent quality; our fluorescence-free gel solutions are recommended for the use of automatic sequencers. Please note The ROTIPHORESE ® acrylamide and bisacrylamide solutions from Carl ROTH are produced only from acrylic acid-free substances and are strictly controlled in acrylamide content and pH. Oxidation products are removed from the solution by a selective absorption process. Their new formation and the polymerization of the solution are prevented by stabilizing the solution with inert gas. In order to ensure a high lot-to-lot consistency of our ROTIPHORESE ® solutions, each batch is subjected to an electrophoretic test. Fluorescence-free gel solutions are tested for suitability for automatic sequencers. ROTIPHORESE ® Gel 40 (37.5:1) ROTIPHORESE ® 40 %, ready-to-use, gas-stabilized Cross linking 2,7.
