| Product Name | FITC-Dextran, 70 kDa |
| Catalog No. | RERE-0148 |
| Description | A fluorescein isothiocyanate conjugate of dextran with an average molecular mass of 70 kDa, positioned in the size window where molecules begin to be restricted by glomerular and vascular barriers rather than passing freely. This mid-range fraction suits permeability comparisons across a molecular-weight ladder, renal clearance selectivity work and retention studies in membrane or tissue models. The conjugate is supplied as a stable solid and is water soluble for direct buffer preparation. |
| Intended Use | Fluorescent tracing of permeability, renal filtration selectivity and barrier retention studies |
| Principle / Technology | Fluorescein label provides green fluorescence for detection while the dextran backbone defines hydrodynamic size and low nonspecific binding |
| Specificity | Average molecular weight 70 kDa; CAS 60842-46-8 |
| Reaction Conditions / Protocol | Dissolve in aqueous buffer at the concentration required by the study design; protect from light during handling and measurement |
| Storage Conditions | 2 to 8°C |
| Package Specifications | 100 mg; 500 mg; 1 g; 5 g |
| Key Features | Mid-range 70 kDa fraction for size-resolved permeability ladders; water soluble solid |
For research use only, not for clinical use.
