m-PEG20000-azide
Based on 1 Customer Validation
m-PEG20000-azide is a PEG derivative. It is a click chemistry reagent. Containing the Azide group, it can undergo a copper-catalyzed azido-azynylene cycloaddition reaction (CuAAc) with molecules containing the Alkyne group. It can also undergo a ring-strain-driven alkyne-azido cycloaddition reaction (SPAAC) with molecules containing the DBCO or BCN groups.

EdU Incorporation Assay (Click Chemistry-Based DNA Synthesis Measurement)
The EdU incorporation assay measures DNA synthesis by adding the thymidine analog 5-ethynyl-2′-deoxyuridine to cells or tissues, where it is incorporated into newly synthesized DNA during S phase. Incorporated EdU is detected by copper-catalyzed azide-alkyne cycloaddition, in which a fluorescent azide covalently reacts with the ethynyl group on EdU, allowing S-phase cells to be detected by fluorescence microscopy, flow cytometry, or high-content imaging. EdU detection does not require DNA denaturation or anti-BrdU antibody access, which preserves sample structure and improves compatibility with immunostaining and multiparameter cytometry compared with BrdU-based detection. EdU can be cytotoxic in a cell-type- and exposure-dependent manner, so pulse duration, concentration, and continuous-labeling designs should be validated for each cell type.
