Immunohistochemistry-Paraffin: Ki67/MKI67 Antibody [NB110-89719] - IHC analysis of a formalin fixed paraffin embedded tissue section of mouse intestine using 1:200 dilution of rabbit anti-KI67 antibody. The staining was developed with HRP labeled anti-rabbit IgG secondary antibody and DAB reagent, and nuclei of cells were counter-stained with hematoxylin. This antibody generated a specific nuclear staining in epithelial cells and the staining was more intense in the cells close to the bases of crypts. Weak to moderate positivity was found at the cytoplasmic level also.

Background: Ki67/MKI67

Ki67 is a nuclear protein associated with proliferation, named after its discovery in a Hodgkin's lymphoma-derived cell line by Scholzer and Gerdes at Kiel University, Germany (1). This proliferation marker is expressed during active phases of the cell cycle (late G1, S, G2 and M), whereas the protein remains undetectable in the G0 phase. Ki67 has two main isoforms with theoretical molecular weights of 319 kDa and 359 kDa. Its abundance is tightly regulated by synthesis and degradation with an estimated half-life of 60-90 min, regardless of its position in the cell cycle. Ki67 has been shown to be involved in ribosomal biogenesis, heterochromatin maintenance, and mitotic chromosome separation (2).

Detection of Ki67 by immunostaining is commonly used as a proliferation marker in solid tumors, as well as certain hematological malignancies (3-5). The Ki67 index, which reports on positive Ki67 stained tumor cell nuclei, has been extensively studied as a prognostic biomarker in cancers such as breast cancer and cervical cancer.
