| Product Name | Fluor 488 EdU Cell Proliferation Assay Kit (Imaging & Flow Cytometry) |
| Catalog No. | RESK-0165 |
| Description | Cell proliferation analysis is a fundamental approach for assessing cell health, genotoxicity, and the efficacy of antitumor drugs. The BrdU assay is a commonly used method for detecting cell proliferation; the EdU assay is an upgraded and breakthrough improvement over the BrdU method. EdU (5-ethynyl-2'-deoxyuridine) is a pyrimidine nucleoside analog that is incorporated into DNA strands during DNA synthesis (S phase). EdU detection is based on click chemistry (copper-catalyzed azide-alkyne cycloaddition). |
| Intended Use | For the detection of cell proliferation and cell cycle analysis by fluorescence microscopy and flow cytometry. For research use only. |
| Principle / Technology | The EdU reagent in the kit contains an alkyne group, while the Fluor 488 Azide dye reagent contains an azide group. Incorporated EdU is labeled rapidly and efficiently through click chemistry (copper-catalyzed azide-alkyne cycloaddition), and only a small amount of the azide dye is needed to efficiently label the incorporated EdU. Standard aldehyde fixation and detergent permeabilization allow the detection reagents to enter the cells, whereas the BrdU method requires DNA denaturation (acid denaturation, heat denaturation, or DNase digestion) to expose BrdU for antibody binding. |
| Detection Method | Fluorescence microscopy and flow cytometry |
| Sample Type | Cultured proliferating cells |
| Performance Range / Specifications | Suitable for both cell proliferation detection and cell cycle analysis; compatible with fluorescence microscopy and flow cytometry. |
| Reaction Conditions / Protocol | 1. Label proliferating cells with EdU. 2. Fix cells with standard aldehyde fixation and permeabilize with detergent. 3. Perform the click reaction with the Fluor 488 Azide detection reagent. 4. Counterstain nuclei with Hoechst 33342 for cell cycle analysis if required. 5. Analyze by fluorescence microscopy or flow cytometry. |
