Acrylamide (electrophoresis grade) is supplied as a powder or a 40% solution in ultrapure water. Bisacrylamide (Bis (N,N’-methylenebisacrylamide)) (electrophoresis grade) is supplied as a powder or a 2% solution in ultrapure water.
Acrylamide/bisacrylamide solutions are available at the most common ratios (37.5:1 or 29:1) for use in protein and nucleic acid electrophoresis. The concentration is based on the total weight of both the acrylamide and bisacrylamide. Supplied as 40% solutions prepared from electrophoresis grade acrylamide and bis-acrylamide in ultra-pure water.
