IHC of Ki-67 on an FFPE Colon Tissue
Intended Use | For In Vitro Diagnostic Use | |||||||||||||||||||||||||||||||||||
Summary and Explanation | The Ki-67 protein is a cellular marker for proliferation. It is strictly associated with cell proliferation. During the interphase, the Ki-67 antigen can be exclusively detected within the cell nucleus, whereas in mitosis most of the protein is relocated to the surface of the chromosomes. Ki-67 protein is present during all active phases of the cell cycle (G1, S, G2, and mitosis), but is absent from resting cells (G0). Ki-67 is an excellent marker to determine the growth fraction of a given cell population. The fraction of Ki-67-positive tumor cells (the Ki-67 labeling index) is often correlated with the clinical course of cancer. The best-studied examples in this context are Carcinomas of the Prostate and the Breast. | |||||||||||||||||||||||||||||||||||
