Drug Target Assay Kit

Bacterial DNA topoisomerase II (gyrase) converts relaxed circular DNA into supercoiled DNA (the DNA supercoiling reaction).

Kit Components

Component GDSA100KE
10 x Buffer 400 µl
Relaxed DNA (250 µg/ml) 105 µl
10 mM ATP 220 µl
5 x Gel loading buffer 550 µl
E. coli gyrase (2000 nM, 100 x) 25 µl

Final reaction conditions: 20 mM Tris-HCl pH 8, 35 mM NH4OAc, 4.6% glycerol, 1 mM DTT, 0.005% Brij35, 8 mM MgCl2, 12.5 µg/ml relaxed plasmid DNA, 1 mM ATP and 20 nM gyrase. A reaction without ATP can serve as negative control.

Assay Principle

Supercoiled and relaxed DNA are separated by agarose gel electrophoresis, so E. coli gyrase activity shows as relaxed plasmid DNA converted to the supercoiled form, visible as separate bands after staining.
