S35 radiolabeling and silver grain emulsion dipping identify mRNA signals in tissue sections. Using either standardized circular regions or free-drawn boundaries, BIOQUANT can analyze the degree of grain labeling in a cell population.

Using a consistent "expression threshold," BIOQUANT rapidly quantifies the area of protein expression in specific anatomical regions.
