The Ki-67 protein (also known as MKI67) is a cellular marker for proliferation, and can be used in immunohistochemistry. It is strictly associated with cell proliferation. During 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 in resting (quiescent) cells (G0). Cellular content of Ki-67 protein markedly increases during cell progression through S phase of the cell cycle. In breast cancer Ki67 identifies a high proliferative subset of patients with ER-positive breast cancer who derive greater benefit from adjuvant chemotherapy.
IF shows positive staining in paraffin-embedded human colon cancer. Anti-Ki67 (Alexa Fluor® 594 Conjugate) antibody was used at 1/200 dilution (magenta) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
