说明

一般說明

Topoisomerase II β (M.W 180 kDa) plays important roles in synthesis and transcription of DNA as well as chromosomal segregation during mitosis. It is present ubiquitously in normal cells and is upregulated in tumors and proliferating cells. Topoisomerase II β is also implicated in drug resistance of tumor cells.

特異性

In Immunoprecipitation and Western blot experiments the Ki-S1 antibody recognizes a major protein of 170 kD which was identified as the a isoform of topoisomerase II (Boege et al., 1995; Kreipe et al., 1993). In addition, it has been shown that the Ki-S1 antibody recognizes a carboxyterminal a-isoenzyme specific epitope missing in topoisomerase IIb (Boege et al., 1995). In immunohistochemistry the Ki-S1 antibody shows strong nuclear staining only in proliferating cells. The epitope recognized by the antibody is also detectable in paraffin-embedded tissue sections (Kreipe et al., 1993). Accordingly, it has been shown that the expression of topoisomerase IIa is strongly restricted to proliferating cells (Tsutsui et al., 1993). The topoisomerase IIa antigen is preferentially expressed during G 1 , S, G 2 and M phase of the cell cycle, while resting, non-cycling cells (G 0 phase) lack topoisomerase IIa. In addition, constantly proliferating cells (e.g. cell lines) react positively to topoisomerase IIa during the entire cell-cycle. This specificity of Ki-S1 antibody for proliferating cells might make it a useful tool for determination of the proliferative fraction in solid tumors such as mammary carcinomas (Kreipe et al., 1993; Sampson et al., 1992; Camplejohn et al., 1993; Kreipe et al., 1993; Rasbridge et al., 1994) and gangliomas (Wolf et al., 1994).
