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[1].
