| Product Name | CFDA SE, Cell Proliferation Tracer, Powder |
| Catalog No. | RERE-0309 |
| Description | CFDA SE fluorescent probe supplied as a 5 mg powder stock for laboratories that prepare their own tracer working solutions. After crossing the cell membrane, intracellular esterases convert the probe into fluorescent CFSE, which couples irreversibly to intracellular proteins and is inherited at half intensity through each cell division, so the same chemistry supports both proliferation tracking and long-term cell labeling. Store at -20 °C away from light; shelf life is 12 months. |
| Intended Use | Stock fluorescent tracer for cell proliferation tracking and long-term cell labeling |
| Principle / Technology | Intracellular esterases transform CFDA SE into fluorescent CFSE that couples covalently to intracellular amines and dilutes with each division |
| Specificity | 5 mg powder; 12 month shelf life |
| Reaction Conditions / Protocol | Dissolve the powder in the required anhydrous solvent shortly before use, avoiding aqueous exposure, then label the cells according to the tracking protocol |
| Storage Conditions | -20 °C, protected from light |
| Package Specifications | 5 mg |
| Key Features | Powder stock for custom working solution preparation; division-diluting fluorescence; 12 month shelf life |
For research use only, not for clinical use.
