INTRODUCTION
Horseradish peroxidase-linked secondary reagents are best used for low-resolution studies that are aimed at the rapid detection of the presence or localization of the antigen. The major advantages of using this detection method are the sensitivity and the ability to observe the results with just a light microscope. Extra sensitivity can be found by observing the precipitated enzyme products by interference reflection microscopy. Aminethylcarbazole (AEC) yields a red product. It is less sensitive than DAB (Detection of Horseradish Peroxidase-Labeled Reagents with Diaminobenzidine/Metal), but can be used when the DAB reaction gives too high a background or if the
