A double-labeling approach was applied to nonisotopic in situ hybridization with individual cosmid and plasmid clones, using digoxigenin or biotin as label and a combination of two separate enzymatic labeling methods. Probe labeling was achieved by nick translation, followed by tailing of the probe by terminal deoxynucleotidyl transferase. The double-labeling method, in conjunction with an improved detection protocol, provides for a higher signal intensity than that obtainable with single-labeled probes.
