DIBA-Cy5
DIBA-Cy5 is a fluorescent DIBA antagonist made up be DIBA-alkyne binding Cyanine5 fluorophores (Cy5) and polyethylene glycol (PEG) biomolecules. DIBA-Cy5 can serve as a fluorescent ligand, suitable for probe attachment through click chemistry. DIBA-Cy5 exerts a high binding affinity to type-2 mAChR (M2R) with the Kd value of 1.80 nM, can directly stain M2R receptors in the sinoatrial node of a mouse heart.

In Vitro
DIBA-Cy5 (0.01 nM-1 mM; 5 h) shows selective binding property for type-2 mAChR (M2R) over M1R, with Kd of 1.08 nM and 104.5 nM, respectively[1].
DIBA-Cy5 (10 nM; 3 h) exerts the competitive binding mode with orthosteric antagonist Atropine (HY-B1205)/allosteric modulator LY2119620 (HY-15885), indicating a dualsteric binding mode of the DIBA-type antagonist to M2R[1].
DIBA-Cy5 (50 nM; 16 h) results direct staining to M2R receptors in the sinoatrial node of a mouse heart. DIBA-Cy5 can be used binding assays that screen compounds for M2R as the receptor target[1].

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.
