pColiExpress™ II Cloning & Expression Kit

pColiExpress™ II Cloning & Expression Kit

For a highly Efficient, Fast & Versatile Protein Expression (T4 DNA Ligase based) in E. coli from PCR fragment cloned

Product Overview:

pColiExpress™ II Cloning & Expression Kit is a DNA Cloning System for Protein Expression in E.coli.  pColiExpress™ technology allows efficiently cloning DNA fragments and the quick production of a large quantity of any desired Protein.

pColiExpress™ II contains all elements required for expression of large quantity of any desired protein by T7 RNA Polymerase Inducible System and a His6 tag at COOH end that allow the protein purification. The vector has also an f1 origin of replication, an ampicillin resistance cassette, and a pBR322 origin of replication.
