| Product Name | Sodium Dodecyl Sulfate (SDS) |
| Catalog No. | RERE-0031 |
| Description | SDS is an anionic detergent used wherever proteins must be denatured, including SDS-PAGE, Western blot sample preparation and DNA extraction. It disrupts intramolecular and intermolecular hydrogen bonds, unfolding proteins and destroying secondary and tertiary structure. Because bound SDS overwhelms the intrinsic charge of the protein, every polypeptide carries a similar charge-to-mass ratio and migrates in the gel strictly according to molecular size. |
| Intended Use | Denaturing protein samples for SDS-PAGE; lysing cells during DNA extraction; general protein denaturation |
| Principle / Technology | Detergent-mediated unfolding of proteins with uniform negative charge coating, enabling size-based electrophoretic separation |
| Sample Type | Protein samples for electrophoresis; cell lysates for nucleic acid preparation |
| Performance Range / Specifications | Purity above 98.5% ensures reproducible electrophoretic mobility and low background |
| Specificity | Broad, non-selective denaturing action on proteins |
| Reaction Conditions / Protocol | Prepare a 10% aqueous stock solution; dilute into sample buffer or extraction mixtures as the protocol requires |
