Abstract
The present invention is generally directed to detectable chemiluminescent acridinium ester labels having hydrophilic modifiers; to compositions, complexes and/or conjugates which include such labels; and to processes for performing bioanalytical assays for target analytes which use such labels. Assays for folate, theophylline, and tobramycin (using such labels with hydrophilic modifiers such as nonionic polyethylene glycol and polyionic spermine disulfonate and polyionic spermine dicarboxylate) are described in detail.
