Ki67 is a cell proliferation marker that is closely related to the cell cycle. There is expression in G1, S, G2, M period,there is no expression in G0 period. Its proliferation index is closely related to the degree of separation, leaching metastasis and prognosis of many tumors.
The Ki67 antigen is a nuclear protein which is expressed in all active parts of the cell cycle (G1, S, G2 and mitosis) but is absent in resting cells (G0). In contrast to many other cell cycle-associated proteins, the Ki67 antigen is consistently absent in quiescent cells and is not detectable during DNA repair processes. Thus, the presence of Ki67 antigen is strictly associated with the cell cycle and confined to the nucleus, suggesting an important role in the maintenance and/or regulation of the cell division cycle.
Disclaimer
Ki67 Antigen is recommended for the detection of specific antigens of interest in normal and neoplastic tissues, as an adjunct to conventional histopathology using non-immunologic histochemical stains.
