Furthermore it is associated with ribosomal RNA transcription.[3] Inactivation of antigen KI-67 leads to inhibition of ribosomal RNA synthesis.[4] Use as cell marker Ki-67 immunostaining of a brain tumour with a high proliferative rate. The Ki-67 protein (also known as MKI67) is a cellular marker for proliferation.[5] 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 from resting cells (G0). Antibody labeling 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, brain and the breast. For these types of tumors, the prognostic value for survival and tumor recurrence have repeatedly been proven in uni- and multivariate analysis. MIB-1 MIB-1 is a commonly used monoclonal antibody that detects the Ki-67 antigen. It is used in clinical applications to determine the Ki-67 labelling index. One of its primary advantages over the original Ki-67 antibody (and the reason why it has essentially supplanted the original antibody for clinical use) is that it can be used on formalin-fixed paraffin-embedded sections, after heat-mediated antigen retrieval (see section Original Ki-67 antibody). Original Ki-67 antibody The Ki-67 protein was originally defined by the prototype monoclonal antibody Ki-67,[6] which was generated by immunizing mice with nuclei of the Hodgkin lymphoma cell line L428. The name is derived from the city of origin (Kiel, Germany) and the number of the original clone in the 96-well plate. Interactions Ki-67 (protein) has been shown to interact with CBX3.[7] See also PCNA - Proliferating Cell Nuclear Antigen, expressed during the DNA synthesis.

The proliferating cells are in the ventricular zone in the neural tube and therefore colored red.
