Enzyme reagent kit ClonExpress II

for PCR

Vazyme ClonExpress II One Step Cloning is a simple, fast, and high efficient cloning technology and enables directional insertion of any amplified DNA product into any linearized vector at any site. Firstly, the vector is linearized at the cloning site. A small sequence overlapped with each end of the cloning site is added onto the insert through PCR. The insert and the linearized vector, with overlapped sequences of 15 bp - 20 bp on both 5’- and 3’-end, respectively, are mixed in an appropriate ratio and incubated with recombinase Exnase II at 37℃ for 30 min. The ClonExpress II is a novel cloning Kit, independent of DNA ligase, significantly reducing the vself-ligated colonies and bringing a true positive rate > 95%. The enhanced Exnase II and highly optimized buffer significantly improve the recombination efficiency and the tolerance to impurities.Both the linearized vector and the PCR products of insert can be directly used for recombination without purification, significantly simplifying the procedures. Product Features Simple, fast, efficient, suitable for any carrier; No need to consider the restriction site carried by the insert; Efficient cloning of 50 bp-10 kb DNA fragments; Linearized cloning vector and PCR products can be cloned directly without purification; No ligase, no self-connection, positive rate >95%.
