Topoisomerase II alpha (Proliferation & Drug-Resistance Marker) (TOP2A/1362) , CF405S conjugate , 0.1mg / mL

This antibody recognizes a 170 kDa protein , which is identified as topoisomerase IIα. It shows no cross-reaction with topoisomerase IIβ or topoisomerase I. Topo IIα plays important roles in synthesis and transcription of DNA as well as chromosomal segregation during mitosis. It is reported to be a sensitive and specific marker of late S- , G2- & M-phases in transformed and developmentally regulated normal cells. Topo IIα is also implicated in drug resistance of tumor cells.Primary antibodies are available purified , or with a selection of fluorescent CF® Dyes and other labels. CF® Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets , because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
