ClonExpress® technology is a simple, fast and efficient DNA seamless cloning technology, which can clone the insert into any position of any vector. Use any method to linearize the vector, and perform forward/reverse PCR on the insert. The 5'end of the primer is introduced into the end sequence of the linearized vector, so that the 5'and 3'ends of the PCR product have the same sequence (15 bp-20 bp) as the two ends of the linearized vector. After the PCR product of the sequence and the linearized vector are mixed in a certain proportion, 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 of recombination cloning kit, ClonExpress® MultiS is specifically optimized for multi-fragment recombination reactions, which can realize sequential splicing cloning of up to five inserts at a time. The unique non-ligase-dependent system of the kit greatly reduces the background of vector self-ligation, and does not need to consider the enzyme cleavage site carried by the insert itself; the highly optimized reaction buffer and the enhanced recombinase Exnase MultiS can significantly improve The recombination efficiency of the clone and the tolerance to impurities make it possible to directly use the linearized vector and insert for recombination cloning without purification, which greatly simplifies the experimental steps.
Multi-fragment splicing cloning can be performed at almost any position of any vector;
No need to consider the restriction site carried by the insert itself;
Sequential splicing of two to five inserts can be realized at one time;
Linearized cloning vector and PCR products can be cloned directly without purification
