Ki-67 (MRQ-64) is an antibody designed to target Ki-67 antigen-a nuclear protein encoded by the MKI67 gene whose presence correlates with G1, S, G2, and the mitotic phases of the cell cycle.1 Though its specific role is largely postulated and still yet to be determined, Ki-67’s presence during cellular division makes it an excellent target for labeling rapidly growing malignancies.2 Given that its presence correlates with cell proliferation, the immunohistochemical labeling of Ki-67 antigen may be useful in characterizing a lesion’s growth fraction. It has been demonstrated that identifying this antigen by IHC is useful in characterizing lesions of the breast, lymphoid cells, astrocytes, and uterus.3-9
