Drug Target Assay Kit

DNA decatenation is an essential step during DNA replication in cells. In humans it is carried out by topoisomerase II, which converts concatenated DNA into decatenated DNA.

Kit Components

Component HDD96KE
10 x Assay buffer 600 µl
50 mM MgCl2 1200 µl
10 x Concatenated DNA (30 µg/ml kDNA) 510 µl
10 x ATP (10 mM) 520 µl
0.5 M EDTA 600 µl
20 x Fluorescence dye 275 µl

Assay Principle

After the topo II reaction, decatenated DNA is separated from concatenated kDNA by vacuum filtration through a TDD filter plate. The decatenated DNA passes into a black 96-well receiver plate and is quantified with a fluorescence dye at 535 nm (excitation 485 nm).
