DBCO-PEG2-NHS ester
Based on 1 Customer Validation
DBCO-PEG2-NHS ester is a click chemistry reagent containing an azide group. DBCO-PEG2-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Biological Activity
Description
In Vitro
Click chemistry is used to describe the selective, modular, wide range and high-yield chemical reactions that allow rapid synthesis of new compounds through heteroatom linking (C-X-C). Bertozzi developed click chemistry in a new dimension—Bioorthogonal chemistry. It is defined as a rapid and selective reaction that does not interfere with biological processes under physiological conditions. Common reaction structures of click chemistry, such as Azide, Alkyne, DBCO, BCN, TCO and Tetrazine.

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.
