Description Quantity discount when you buy 4 or more 1 liter bottles!Catalog number:EC-89037.5:1 Acrylamide to Bisacrylamide Stabilized SolutionOptimized for SDS-PAGE of Proteins (Laemmli gels)Consistently Crystal Clear Gels, Zero FluorescenceStabilized for Long Shelf LifeNational Diagnostics ProtoGel forms an electrophoresis matrix that is ideal for the separation of proteins and polypeptides. ProtoGel is a stabilized, ready-to-use 30% (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 Rfvalues. With ProtoGel, you can trust that your results will be consistent one electrophoretic run to the next.Storage:ProtoGel is stable for 24 months when stored tightly capped in a dark area at room temperature (20°C).
