Ambion Acrylamide/Bis 19:1 is a 40% (w/v) solution of acrylamide (38%) and bis-acrylamide (2%) ideal for use in ribonuclease protection assay, sequencing gels, and sizing DNA or RNA fragments. 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.
