Abstract
Fluorescent in situ hybridization (FISH) is an important tool for zebrafish research, particularly when observing the expression of two different genes in the same embryo. Peroxidase-catalyzed deposition of tyramide-conjugated dyes is a widely used and cost-effective approach to performing FISH. A major limitation of the technique is that it does not work well for weakly expressed genes. Here we present a method adapted from planarian research for use in zebrafish that provides a dramatic enhancement of weak staining. By iterating the antibody staining and development steps, a strong signal can be obtained from probes that were previously too weak to detect.
