the specificity of the hybridization was controlled by using 35s-labeled plasmid transcripts as a negative control , while rna preservation in the tissue sample was assessed by using 35s-labeled anti-sense transcripts of a murine 28s rrna clone . c-myc rna was detectable in all the carcinomas ( eight ) and villous adenomas ( four ) , but steady-state levels varied from high to low in different tumors with similar histology .
