Abstract
Chemiluminescent acridinium-9-carboxamide probes containing 1, 3, 9, and 27 phenylboronic acids were prepared and their chemiluminescent properties evaluated. The relative chemiluminescent signal from the probes varied from 4 to 0.83 x 10(19)counts/mol across the series, while the apparent affinity of the probes for the diabetes marker glycated hemoglobin increased from 211 to 0.43 microM. The dose-dependent modulation of the chemiluminescent intensity of the probes upon binding was used to demonstrate a homogeneous assay for glycated hemoglobin.
