compound introduction
Product Info Included Materials: 10X assay buffer and dilution buffer is included. Description High purity, catalytically active Top1 Enzyme overexpressed in the baculovirus system and purified to single band homogeneity. These preparations are cheaper than native topo I made from human tissue and offer excellent purity and high specific activity. In addition, the 100 kDa form of recombinant topo I is stable and is less prone to proteolysis, relative to the native protein from human cells. Shipping&storage The enzyme is shipped on dry ice and should be stored at -20°C. It has a life-time of about 6 months when stored under optimal conditions. Repeat freeze/thaw cycles will accelerate loss.
