Knockout Validated: Ki67/MKI67 Antibody (8D5) [NBP2-22112] - Detection of Ki67/MKI67 by Simple WesternTM. Simple Western lane view shows lysates of HeLa parental cell line and Ki67 knockout (KO) HeLa cell line. A specific band was detected for Ki67/MKI67 at approximately 317 kDa (as indicated) in the parental cell line, but is not detectable in the knockout HeLa cell line using 1:100 of Mouse Anti-Ki67/MKI67 Monoclonal Antibody (Catalog # NBP2-22112). GAPDH is shown as a loading control. This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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.
