Fig. 2. In situ hybridization using Metallothionein (MT) antisense (a), MT
sense (b), and 28S rRNA antisense (c) oligo-DNA probes in paraffin sections
of the esophageal cancer. (a): positive staining was found in the cancer. (b):
no positive staining was detected in the same section. (c): Adequate amounts
of hybridizable RNAs were detected in paraffin section.
