pColiExpress™ IV LIC Cloning & Expression Kit

pColiExpress™ IV LIC Cloning & Expression Kit

For a highly Efficient & Versatile Protein Expression (LIC technology based) in E. coli from PCR fragment cloned

Product Overview:

pColiExpress™ IV 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 the expression of large quantities of any desired protein by the T7 RNA Polymerase Inducible System, and a His6 tag at COOH end of the protein that allows the purification. It contains at the NH2 end the Cmyc tag followed by a 3C from human Rhinovirus (HRV) Protease cleavage site, too. The vector has also an f1 origin of replication, an Ampicillin resistance cassette, and the pBR322 origin of replication.
