Thermo Scientific™ Ammonium Persulfate, 4 x 25 g

High-Purity Oxidizing Agent for Acrylamide Polymerization in Electrophoresis Applications

Thermo Scientific™ Pierce™ Ammonium Persulfate (APS) is a high-purity oxidizing agent used in conjunction with TEMED (N,N,N',N'-tetramethylethylenediamine) to catalyze the polymerization of acrylamide and bisacrylamide during the preparation of polyacrylamide gels for protein and nucleic acid electrophoresis.

APS is essential in initiating free-radical formation, which drives the gel matrix formation. With ≥98.0% purity and low insoluble content, it ensures consistent, reproducible polymerization and uniform gel structure.

Key Features & Benefits

• Electrophoresis-Grade Purity – ≥98% purity with ≤0.005% insolubles for optimal gel consistency
• Efficient Polymerization Catalyst – Works synergistically with TEMED to initiate acrylamide gel formation
• Reliable Gel Formation – Supports high-resolution separation of proteins and nucleic acids
• Powder Form – Allows flexible concentration preparation and longer shelf life
• Multipack Format – Convenient 4 × 25 g bottles for routine lab use

Applications

• Preparation of polyacrylamide gels for SDS-PAGE and native PAGE
• Polymerization of gels for protein electrophoresis, DNA/RNA analysis
• Use in gel-based purification, western blotting, and other downstream proteomics workflows

Chemical & Technical Specifications

Thermo Scientific™ Pierce™ Ammonium Persulfate is a reliable, lab-grade polymerization initiator designed for the efficient and reproducible preparation of polyacrylamide gels.
