| Product Name | PBS-EDTA Buffer, 4× PE, pH 7.4, Sterile |
| Catalog No. | RERE-0437 |
| Description | The pH 7.4 grade of the 4× PE series pairs standard physiological buffering with EDTA's cation-scavenging power, so diluted stock behaves like cells expect while stripping away the calcium and magnesium that anchor cell-cell contacts. Beyond dissociation support, it serves assays that examine the import of nuclear material, where controlled chelation is part of the experimental design. Sterile and room-temperature stable, it waits on the shelf without complaint. |
| Intended Use | Metal ion chelation at physiological pH, including assays of nuclear material import. |
| Principle / Technology | EDTA binds divalent cations against a phosphate-buffered physiological background. |
| Specificity | 4× concentrate; composed of disodium hydrogen phosphate, sodium dihydrogen phosphate and EDTA; pH 7.4; sterile. |
| Reaction Conditions / Protocol | Dilute fourfold with water before use to reach working strength. |
| Storage Conditions | Room temperature; 12 months. |
| Package Specifications | 500 mL |
| Key Features | Physiological pH concentrate; chelation built in; sterile with long shelf life. |
