The antibody binds to a formalin-resistant epitope of the Ki-67 antigen. The immunoreactivity of Ki-S5 is confined to the nuclei of proliferating cells and no crossreactivity with cytoplasmic antigens of epithelial occurs even after antigen retrieval (Mauri et al., 1984). A comparison of immunohistochemical labeling of fresh and fixed tissue samples of NHL showed that identical results were obtained with Ki-67 and Ki-S5 (Kreipe et al., 1993). The Ki-67 antigen is preferentially expressed during late G1, S, G2 and M phase of the cell cycle, while resting, non-cycling cells (G0 phase) lack the Ki-67 antigen. In addition, constantly proliferating cells (e.g. cell lines) react positively to Ki-S5 during the entire cell-cycle. This specificity of Ki-S5 antibody for proliferating cells might make it a useful tool for determination of the proliferative fraction in tumors such as Non-Hodgkin's lymphoma (Kreipe et al., 1993), mammary carcinomas (Mauri et al., 1984), ovarian tumors (Ballin et al., 1994) and prostate cancer.

View All» Clone: Ki-S5 View All» Isotype: IgG1 View All» Background Information: Ki67 antigen is the prototypic cell cycle related nuclear protein, expressed by proliferating cells in all phases of the active cell cycle (G1, S, G2 and M phase). It is absent in resting (G0) cells. Ki67 antibodies are useful in establishing the cell growing fraction in neoplasms (immunohistochemically quantified by determining the number of Ki67 positive cells among the total number of resting cells = Ki67 index). In neoplastic tissues the prognostic value is comparable to the tritiated thymidine labelling index. The correlation between low Ki67 index and histologically low grade tumours is strong. Ki67 is routinely used as a marker of cell cycling and proliferation. This specificity of Ki-S5 antibody for proliferating cells might make it a useful tool for determination of the proliferative fraction in tumors such as Non-Hodgkin's lymphoma (Kreipe et al., 1993), mammary carcinomas (Mauri et al., 1984), ovarian tumors (Ballin et al., 1994) and prostate cancer.
