ABSTRACT:
Colorimetric detection of bindable substances such as antibodies and antigens using chromogens of improved sensitivity and stability. The chromogens take the form of activated solutions containing tetramethylbenzidine or water soluble derivatives of tetramethylbenzidine. Such chromogens are of particular use in home testing applications for detection of antigens such as human chorionic gonadotropin, human luteinizing hormone, and gonococcus bacteria, as well as the detection of antibodies for these substances.
