Specificity / Sensitivity
Ki-67 (D3B5) Rabbit Monoclonal Antibody recognizes endogenous levels of total Ki-67 protein.
Species Reactivity: Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant protein fragment corresponding to residues near the central region of human Ki-67 protein.
Background
Ki-67, named after the location where it was discovered (Kiel University, Germany), is a nuclear nonhistone protein (1) that is universally expressed among proliferating cells and absent in quiescent cells (2). Ki-67 detects proliferating cells in G1, S, G2, and mitosis, but not in the G0 resting phase. Research studies have shown that high levels of Ki-67 are associated with poorer breast cancer survival (3). Research studies have explored the use of Ki-67, along with other markers, as potential prognostic or predictive markers in breast cancer and other malignant diseases (4).
