Description

SDS (Sodium dodecyl sulfate) coats proteins and DNA giving them a negative charge which allows travel through an electrical field towards the anode. TOKU-E SDS, Dust-Free™ Ultrapure is ≥99.5% pure.

TOKU-E Dust-Free™ SDS is an innovative pellet form of SDS specifically 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 which can be especially harmful to those with respiratory complications. By using Dust-Free™ SDS, the inevitable dust-related issues are essentially eliminated. In addition, our R&D team has shown Dust-Free™ SDS dissolves 50% faster than standard powder SDS.

TOKU-E also manufactures and supplies ultrapure, powder SDS.

This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees. Please contact us for specific questions.

    CAS Number

    151-21-3

    Molecular Formula

    C12H25NaSO4

    Molecular Weight

    288.38

    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 to run through electrophoresis gels.

    Storage Conditions

    ≤30°C

Applications

    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.

    Microbiology Applications

    Sodium dodecyl sulfate can be used as a selective agent/supplement to inhibit the growth of non-coliform organisms.
