The antibody labels Ki67 (Clone GM010 also known as GM001), aproliferationassociatednuclearproteinexpressed during all active phases of the cell cycle. Quantitative determination ofthe fraction of cells, which stain positive for the Ki67 nuclear antigen, has been demonstrated to be a highly accurate way of assessing the fraction of proliferating cells within a given tissue.
