Enzyme reagent ClonExpress MultiS

for PCR

The ClonExpress technology is simple, fast, and highly efficient DNA seamless cloning technology. It enables directional cloning of inserts into any site in any vector. Use any method to linearize the vector, and introduce the end sequence of the linearized vector at the 5' end of the insert forward/reverse amplification primer, so that the 5' and 3' ends of the PCR product have the same ends sequence (15 - 20 bp) as the linearized vector, respectively. The PCR product and the linearized vector are mixed in a certain proportion. Under the catalysis of recombinase, the transformation can be performed at 37°C for 30 min to complete the directional cloning. ClonExpress MultiS is a new generation of recombinant cloning kit. It is specifically optimized for multi-fragment recombination reactions, enabling up to five inserts to be cloned at one time. This kit has a unique ligase-independent system, which significantly reduces the self-ligation background of the vector, and does not need to consider the restriction endonuclease sites of inserts. Highly optimized reaction buffer and enhanced recombinase Exnase MultiS can significantly improve the recombination efficiency and the tolerance to impurities. These features makes it possible to use linearized vectors and inserts directly for recombinant cloning without purification, which significantly simplifies the experimental steps. Features Good performance: No ligase, no self-ligation, positive rate >95% Broad Compatibility: Efficient cloning of 50 bp - 10 kb DNA fragments; applicable for 2 - 5 fragments Additional features: No need to consider the restriction site of insert fragments
