| Product Name | FITC-Dextran, 40 kDa |
| Catalog No. | RERE-0147 |
| Description | A mid-range FITC-dextran tracer at 40 kDa, sized to probe filtration barriers that discriminate between small and albumin-scale solutes. In renal research it serves as a marker of glomerular size selectivity, complementing inulin-type clearances, while in epithelial and endothelial permeability models it bridges the gap between the 10 kDa and 70 kDa grades. The fluorescein label supports direct fluorescence quantification in plasma and urine without additional derivation steps. |
| Intended Use | Glomerular size-selectivity, renal clearance and epithelial/endothelial permeability assays |
| Principle / Technology | Fluorescein-labelled 40 kDa dextran traverses and is cleared by size-dependent routes; fluorescence tracks its distribution |
| Sample Type | Plasma and urine from tracer-dosed animals, plus transwell and barrier-model compartments |
| Specificity | Molecular weight 40 kDa; FITC-labelled dextran; read on FITC channels (Ex/Em about 490/520 nm) |
| Reaction Conditions / Protocol | Dose the tracer, collect timed plasma and urine or compartment samples, and quantify by fluorescence against standards |
| Storage Conditions | 2 to 8°C |
| Package Specifications | 100 mg; 500 mg; 1 g; 5 g |
| Key Features | Mid-size tracer bridging small and albumin-scale grades; four pack sizes to 5 g; direct fluorescence readout |
| Readouts / Downstream Assays | FITC-channel fluorescence (Ex/Em about 490/520 nm) |
For research use only, not for clinical use.
