Acridinium Alkyne

Acridinium is a univalent radical derived from acridine. Acridinium alkynes are synthetic molecules known for their strong chemiluminescence, commonly used to label azides on peptides, antibodies, and other biomolecules through copper-catalyzed click reactions. The chemiluminescence of acridinium maleimides is triggered by exposure to an alkaline hydrogen peroxide solution, facilitating their use in sensitive detection methodologies within immunoassays and various biological assays. For accurate signal detection in a chemiluminescence analyzer, a trigger solution containing (A) 0.1% H₂O₂ and 0.1 M HNO₃, and (B) 0.25 M NaOH and 2% Triton X-100 is recommended.
