    Sodium Dodecyl Sulfate (SDS), Dust-Free™ Ultrapure

    $46.10 - $167.20

    Sodium Dodecyl Sulfate (SDS), Dust-Free™ Ultrapure is an innovative pellet form of SDS designed to prevent aerosolized dust when preparing SDS solutions. Dust inhalation from standard grade SDS can lead to coughing, shortness of breath, and nasal passage irritation.  Our R&D team has shown Dust-Free™ SDS dissolves 50% faster than powder SDS.

    Dust-Free™ SDS coats proteins and DNA giving them a negative charge allowing travel towards the anode during gel electrophoresis.  The product is ≥99.5% pure.

     

    Mechanism of Action Sodium Dodecyl Sulfate works by denaturing proteins but does so without breaking peptide bonds. Once proteins are denatured, they carry the highly negative charge they acquired from the SDS, changing their shape and making them more suitable for gel electrophoresis.
    Microbiology Applications Sodium Dodecyl Sulfate can be used as a selective agent/supplement to inhibit the growth of non-coliform organisms.
    Electrophoresis Applications Dust-Free SDS is used in several electrophoresis applications including SDS-PAGE gel construction, running buffers, and DNA and protein preparation and denaturing.
