ClonExpress Ultra One Step Cloning Kit is a new generation of recombinant cloning kits, compatible with 1 - 5 fragments homologous recombination. The unique ligase-independent system of this kit significantly reduces the self-ligation background of the vector. Restriction endonuclease sites do not need to be considered. Highly optimized 2 × ClonExpress Mix (It contains enhanced recombinase Exnase) can significantly improve the recombination efficiency and the tolerance to impurities. pCE-Zero vector is compatible with most PCR products, enabling the specific PCR products to be used directly for recombination without any treatments, which significantly simplify the procedure.
