ClonExpress® technology is a simple, fast and efficient DNA seamless cloning technology, which can clone the insert into any position of any vector. Linearize the vector and place the insert 5’in the forward/reverse PCR primer Introduce the end sequence of the linearized vector into the end, so that the 5’and 3’ends of the PCR product have the same sequence as the two ends of the linearized vector (15 bp-20 bp). This PCR product and the linearized vector are in a certain ratio After mixing, under the catalysis of the recombinase, the reaction can be carried out at 37°C for 30 min to complete the directional cloning.
As a new generation recombinant cloning kit, ClonExpress® II has a unique non-ligase dependent system, which greatly reduces the background of vector self-ligation, and the positive rate can reach more than 95%. The highly optimized reaction buffer and the enhanced recombinase Exnase II significantly improve the recombination efficiency of cloning and the tolerance to impurities, making it possible for linearized vectors and inserts to be directly used for recombination cloning without purification, greatly simplifying The experimental steps.
