Single paraffin wax block / cell FFPE block.
A single FFPE block is comprised of a two cell line plugs selected for demonstrating differential MLH1 protein IHC staining, demonstrating complete loss of nuclear expression (deficiency or loss type expression) of MLH1 protein and intact nuclear expression of MLH1 protein in other plug.
