Topo II Buffer is supplied as a 10x Stock solution in two parts that must be mixed prior to use:
These two buffers must be mixed to prepare a final 5X working stock of assay buffer. Furthermore, the final 5X Complete Buffer contains both A and B and should be made fresh for each experiment. Do not freeze the 5X Complete Buffer; it is stable for 24 hours on ice. To Prepare the 5X Complete Buffer, mix equal volumes of A and B (0.1ml of A and 0.1ml of B) and place at 4° C or on ice.
Quality Control Analysis:
The 5X Complete Topo II Assay Buffer (containing equal parts A and B above) is optimized and tested for decatenation and relaxation activity of eukaryotic topo II. The Complete Buffer should be made fresh for each
The two-part buffer is shipped at room temperature (or on dry ice if included with enzyme) but should be stored at -20°C. The 5X Topo II Complete Assay Buffer is stable for 24 hours at 4°C.
