VWR Sodium dodecyl sulfate (SDS) ≥98%, GPR RECTAPUR®

VWR Sodium Dodecyl Sulfate (SDS) ≥98%, GPR RECTAPUR® is a high-purity, analytical-grade anionic surfactant widely employed across molecular biology, biochemistry, and life sciences research. Also known as sodium lauryl sulfate, SDS is characterized by its amphiphilic molecular structure—comprising a long hydrophobic hydrocarbon tail and a hydrophilic sulfate group. This dual nature enables SDS to disrupt hydrophobic interactions in proteins, lipids, and cell membranes, making it an effective detergent and protein denaturant.

Its ≥98% purity ensures consistency and reliability in highly sensitive experimental workflows, particularly where trace contaminants can interfere with data quality or assay performance.

Key Features & Benefits

✅ ≥98% Purity (GPR RECTAPUR® Grade)

Ensures reproducible results across various analytical techniques, including protein electrophoresis and nucleic acid extraction.

✅ Anionic Surfactant with Strong Detergent Action

Efficiently disrupts lipid membranes and denatures proteins by interfering with hydrophobic and ionic interactions.

✅ Validated for SDS-PAGE

Enables accurate separation of proteins by molecular weight during sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE).

✅ Versatile Molecular Biology Tool

Supports DNA/RNA extraction, hybridization assays, PCR protocols, and membrane protein solubilization.

✅ Low Heavy Metal Contamination

Tested to ensure minimal interference in trace-sensitive applications.

✅ Suitable for Research and Industrial Use

Applicable in academic, pharmaceutical, agricultural, and industrial laboratories.
