ProtoGel (40% Solution at 37.5:1 Ratio)

ProtoGel forms an electrophoresis matrix that is ideal for the separation of proteins and polypeptides. ProtoGel is a stabilized, ready-to-use 40% (w/v) acrylamide/methylene bisacrylamide solution (37.5:1 ratio), manufactured from the highest quality materials, from which virtually all impurities have been removed. ProtoGel has zero acrylic acid content, eliminating the fixed charges that cause band streaking. Additionally, oxidation products such as aldehydes have been removed by a selective adsorption process; aldehydes can attack proteins, altering the structure of the sample, and thus altering Rf values.
