Abstract
The invention provides methods for detecting a labeled sample molecule bound to an immobilized probe by electrochemiluminescence. The method comprises providing a multiplexed molecular analysis system comprising a reaction chamber comprising a reaction substrate comprising a plurality of biosites, each biosite comprising a plurality of similar capture probes attached to the reaction substrate, the reactions substrate comprising an embedded conductive material connected to an electrical source and providing a sample comprising a plurality of molecules labeled with a electrochemiluminescent label; adding a solution comprising this sample to the reaction chamber; applying a voltage from the electrical source to the conductive material after sufficient time has passed for a labeled molecule to bind to a capture probe, thereby inducing an electrochemical event within the electrochemiluminescent label that releases a detectable amount of electromagnetic energy; and, detecting the released electromagnetic energy.
