INTRODUCTION
Horseradish peroxidase-linked secondary reagents are best used for low-resolution studies that are aimed at the rapid detection of the presence or the 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. Diaminobenzidine (DAB) is one of the most sensitive substrates for horseradish peroxidase, and it can be made more sensitive by adding metal salts such as cobalt or nickel to the substrate solution. The products are stable in both water and alcohol. For indirect detection using fluorochrome-labeled reagents, see Indirect Detection Using
