Abstract: An in vitro method of making a homogenous cell block for use as a positive control for biomarkers in immunohistochemistry experiments, such slide scanning and image analysis. The homogenous cell block is produced using a three layered vertical apparatus to create an evenly distributed suspension of FFPE cells, wherein the cells are mixed with 3% agarose while still rotating within the apparatus's middle layer. The injection of the cell mixture into a mold creates a homogeneous cell block where each cell, or ratio of different types of cells, is evenly distributed. The cell mixture within the cell block may comprise: a mixture of the same type of cell with different genetic modifications; a mixture of the same type of cell with different protein or nucleic acids expression; and a mixture of different types of cells with different genetic backgrounds, and/or different expression level of genes and/or proteins.
