Here we will focus exclusively on gel electrophoresis of proteins. Gel electrophoresis can be used to determine: the purity of a protein sample. heterogeneity and extent of degradation of a protein sample.

    2011-8-15 · Plasmid DNA minipreps are fundamental techniques in molecular biology. Current plasmid DNA minipreps use alkali and the anionic detergent SDS in a three-solution format. In addition, alkali minipreps usually require additional column-based purification steps and cannot isolate other extra-chromosomal elements, such as bacteriophages. Non-ionic detergents (NIDs) have been used …

  • POLYPRO Anionic and Nonionic Polymers Data Sheet

    2017-9-26 · POLYPRO anionic and nonionic polymers are high molecular weight, water-soluble flocculating agents made by the co- polymerization of acrylamide with itself or various anionic (negatively charged) monomers. These polymers are available in both liquid emulsion and granular dry solid grades and cover the full spectrum of charges from 0 to 100%.

    Polyacrylamide - Uses of polyacrylamide. One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called ...
