Iodoacetamido-PEG6-azide
Iodoacetamido-PEG6-azide is an aqueous soluble PEG linker containing an azide and a terminal Iodoacetamido group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Iodoacetamido moiety is commonly used to bind covalently with the thiol group of cysteine so the protein cannot form disulfide bonds.

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.
