| Product Name | FITC-Dextran Sulfate, 500 kDa |
| Catalog No. | RERE-0133 |
| Description | A 500 kDa fraction of fluorescein-labelled dextran sulfate, sized for studies that require a tracer retained behind intact barriers: only where permeability has been compromised does the molecule cross. The high molecular weight also suits plasma volume and regional perfusion measurements where prolonged intravascular persistence is wanted. Fluorescein excitation and emission support reading on standard fluorescence instrumentation. |
| Intended Use | High-molecular-weight fluorescence tracing of barrier integrity and regional perfusion |
| Principle / Technology | Fluorescein signal reports the distribution of the 500 kDa dextran sulfate fraction |
| Sample Type | Barrier integrity assays, perfusion and volume studies |
| Specificity | Nominal 500 kDa; fluorescein-labelled sulfated dextran |
| Reaction Conditions / Protocol | Reconstitute protected from light and apply at the concentration the assay requires |
| Storage Conditions | Protect from light; -20°C; under argon |
| Package Specifications | 100 mg; 250 mg; 500 mg; 1 g |
| Key Features | Retained by intact barriers; suitable for vascular persistence studies |
| Readouts / Downstream Assays | Fluorescein excitation/emission on standard fluorescence platforms |
For research use only, not for clinical use.
