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.

Antigen retrieval using 10mM sodium citrate may enhance the signal. The staining may not work good in adult tissues using the vibratome tissues. Standardisation for adult brain tissues would be required.
FAQs for Ki67/MKI67 Antibody (NB600-1252). (Showing 1 - 2 of 2 FAQs).
I have bought via kristalindo biolab (Indonesia) primary antibody ki-67 (catalog # NB600-1252). Do you have a positive control for that ? My sample is breast cancer from rat.
In our lab, we have tested this product in tonsil tissues and we recommend either using a tonsil tissue from rat or human as a positive control to determine that the staining you see in your rat breast cancer tissue is specific. We do have a tonsil slide that you might find useful (catalog # S152W0).
I am using the Ki-67 antibody (NB600-1252) and I need some information about the protein concentration.
Please note that this product is a "Tissue Culture Supernatant" production and the exact concentration of the antibody is not quantifiable in it. Technically speaking, the tissue culture supernatants can have the IgG contents from 1 - 3 mg/ml.
