T7 cloning and expression systems: Expresso

The Expresso® T7 cloning and protein expression systems from Lucigen are designed for fast, easy and efficient directional cloning and expression of PCR-amplified genes. The systems are complete with pre-processed pETite™ N- or C-His cloning vectors, and two competent cell lines, supplied in single transformation vials. The Expresso T7 cloning and protein expression systems uses Expressioneering Technology™, an enzyme-free recombinational cloning strategy to seamlessly integrate the gene with the vector

Benefits of using the Expresso cloning and protein expression systems
• Enzymo-free cloning in seconds with cloning-ready vector and cells
• High efficiency: >90% recombinants
• Tightly-controlled expression of N- or C- terminal 6xHis tagged protein
• SUMO tag vector available for low solubility protein expression

Pre-processed pETite C-His vector was mixed with 1 µl of unpurified PCR gene product and transformed into HI-Control 10G Chemically Competent Cells. Colony PCR was performed on 18 randomly chosen colonies; 17 of 18 contained insert of the correct size.

Expresso T7 system
Contains pre-processed pETite® N-His and/or pETite C-His Vector DNA, two competent cell lines optimised for cloning and expression and N-His and/or C-His Posi pre-processed pETite™ N- or C-His cloning vectors.

Expresso T7 SUMO system
Contains pre-processed pETite® N-His SUMO Vector DNA, two competent cell lines optimised for cloning and expression, SUMO Positive Control C Insert DNA, transformation positive control pUC DNA, SUMO Express Protease, SUMO Cleavage Control Protein and forward and reverse PCR primers to confirm clones.
