Takara pCold III DNA \25 ug

Takara Takaras pCold Expression Vectors offer cold shock expression technology for high purity, high yield protein production. The series includes four different vectors that utilize the cold shock Protein A (cspA) promoter to direct expression of recombinant protein in E. coli. These vectors selectively induce target protein synthesis at low temperatures (15°C) when the synthesis of other proteins is suppressed and protease activity is decreased. This results in high yield of the target protein (60% of intracellular protein). In addition to the cspA promoter, all four vectors contain a lac operator (for control of expression), ampicillin resistance gene (amp^r), ColE1 origin of replication, M13 IG fragment, and multiple cloning site (MCS). Furthermore, pCold III DNA also contains a his tag sequence and a Factor Xa cleavage site. These vectors work equally well for synthesis of non-labeled and radiolabeled proteins and can be used in conjunction with Takaras Chaperone Plasmid Set (Cat.# 3340).Note: Licensing agreement is required.
