Topoisomerase II (Topo II) is a nuclear enzyme that regulates the topological states of DNA by transient breakage and rejoining double-stranded DNA, catalyzing the decatenation and unknotting of topologically linked DNA circles and the relaxation of supercoiled DNA. In mammalian cells, Topo II consists of two isozymes, Topo IIα (170 kDa) and Topo IIα (180 kDa). Expression and localization of each isoform are distinct and stage specific during the cell cycle. Topo IIα is expressed constantly throughout cell cycle, whereas the expression of Topo IIα is cell cycle-regulated, peaking in G2 to M phase and declining to a minimal level at the end of M phase. It is considered that Topo IIα plays an essential role in cell proliferation, especially during late S to M phase.

This antibody was purified from mouse ascites fluid using protein A agarose. This hybridoma was established by fusion of mouse myeloma cell Sp2/0-Ag14 with Balb/c mouse splenocyte immunized with the recombinant human Topoisomerase IIα protein corresponding to C-terminal 182 aa.
