Ambion® 6% Denaturing Acrylamide Gel Solution is a 19:1 solution of acrylamide (38%), bis-acrylamide (2%), and 6M urea ideal for use with RPA analysis and gel purification of probes. Supplied in one bottle containing 450 mL. The solution is provided in a ready-to-use form, reducing the dust, inhalation, and contact hazard associated with weighing and preparing acrylamide and bis-acrylamide powders and solutions. Concentrations are carefully controlled and all solutions are micro-filtered prior to packaging. All Ambion® acrylamides are rigorously tested for contaminating non-specific endonuclease, exonuclease, and RNase activity, and for functionality.
