FIG. 3.

Cytological localization of the p38 MAPK and MKK genes. Chromosome in situ hybridization was performed with digoxigenin-labeled cDNA probes on samples prepared from wild-type larval salivary glands. After hybridization with the probes, the samples were incubated with antidigoxigenin antibodies, which were conjugated with horseradish peroxidase. The hybridized probe, visualized with a peroxidase reaction, is indicated by the arrowheads. The locations of the genes for the MAPKs and the upstream kinases are summarized in the table.
