Research Antibiotics, Sodium Dodecyl Sulfate Dust-Free Pellets, 250 grams

Sodium Dodecyl Sulfate (SDS), Dust-Free™ Ultrapure, 250 gram. SDS (Sodium dodecyl sulfate) coats proteins and DNA giving them a negative charge which allows travel through an electrical field towards the anode. Dust-Free™ Ultrapure is ≥99.5% pure. 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. Dust-Free SDS dissolves 50% faster than standard powder SDS.

This product is considered a dangerous good. Quantities above 1 g may be subject to additional shipping fees.

• Category: Electrophoresis Reagents
• 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

Specifications

• Form: pellets
• Appearance: White rod
• Impurity Profile: Chloride: ≤0.01%
• Water Content (Karl Fischer): No more than 2.0%
• Absorbance 20% in H2O: 280nm: ≤0.28, 410nm: ≤0.1
• Assay ≥99.5% (Titration)
• Sulfated Ash 21.5-27.5%
• Heavy Metals: Lead: ≤2ppm

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.
