Methods, reagents, kits and systems are disclosed for determining an analyte in a sample suspected of containing the analyte where all reagents are soluble in aqueous solution. One assay method includes treating a sample suspected of containing the analyte under conditions such that if the analyte is present, an activator is brought into reactive configuration with a chemiluminescent compound to activates it. The sample is also treated with an agent to reduce signal not related to analyte. Finally, the sample is treated with a trigger solution thereby producing light from the activated chemiluminescent compound. No reagents are associated with a surface or other solid phase.

A method for enhancing the chemiluminescent signal of a chemiluminogenic compound in a chemiluminescent reaction mixture in a chemiluminescent reaction which has a step of oxidizing the chemiluminogenic compound in the presence of an effective amount of an enhancer can be performed. To obtain an enhanced chemiluminescent signal, a compound selected from the group of quaternary amine cationic substances of formula (I) for enhancing the chemiluminescent signal of an acridinium compound is used, preferably an acridinium ester or an acridinium sulfonamide. The signal is obtained in a chemiluminescent reaction, preferably in a chemiluminescent immunoassay, a related chemiluminescent composition and a related kit.
