pColiExpress™ II LIC Cloning & Expression Kit
For a highly Efficient & Versatile Protein Expression (LIC technology based) in E. coli from PCR fragment cloned
pColiExpress™ II LIC Cloning & Expression Kit is a highly efficient, versatile and fast system of DNA cloning vectors for protein expression in E. coli. All family systems are based in directional ligase-independent-cloning (LIC) technology, a rapid procedure that provides high-cloning efficiencies and the fast production of a large quantity of any desired protein.
It contains all elements required for expression of large quantities of any desired protein by T7 RNA Polymerase Inducible System and a His6 tag at the COOH end of the protein that allows the purification. The vector has also an f1 origin of replication, an Ampicillin resistance cassette, and the pBR322 origin of replication.Quote request
