The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a feline-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies. The parent antibody, Ki-67 (D3B5) Rabbit mAb #9129, is produced by immunizing animals with a recombinant protein fragment corresponding to residues near the central region of human Ki-67 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nKi-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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nantigen identified by monoclonal antibody Ki-67; Antigen KI-67; Antigen Ki67; KI-67; KI67; KIA; marker of proliferation Ki-67; MIB-; MIB-1; MKI67; PPP1R105; Proliferation marker protein Ki-67; proliferation-related Ki-67 antigen; protein phosphatase 1, regulatory subunit 105\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nSource\/Isotype: Feline chimeric IgG1","brand":"CST","offers":[{"title":"Default Title","offer_id":46800294674601,"sku":"43021S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-43021s","provider":"Iright","version":"1.0","type":"link"}
