Tissue print and print-phoresis. (A) Photograph of two representative core needle biopsies. (B) The biopsy prints were incubated with 0.1% toluidine blue solution for five minutes. After two washing in phosphate buffer the prints were visualized as blue regions. (C) Schematic representation of the SDS-PAGE print-phoresis. Biopsy print has been put on the top of the resolving gel, and embedded in the stacking gel. Representative resolving gels were stained with Coomassie blue (left) or with silver solution (right) in order to visualize the protein content. On the top of each gel the position of the tissue print is shown.
