Expressioneering: Restriction Enzyme Free E. coli Cloning and Expression System including Solubility
Expresso® Solubility and Expression Screening System
Multiplex Protein Solubility Screen
One convenient screening kit containing 7 fusion tags proven to increase protein expression and solubility
•Use one amplicon to simultaneously generate all your constructs
•Rapid, simultaneous protein screening with TEV-cleavable fusion tags
•PCR to protein in as little as 4 days
The Expresso® Solubility and Expression Screening System is an all-in-one system that enables PCR amplification, rapid cloning, and expression of your protein of interest with a diverse panel of powerful and cleavable solubility tags. Lucigen has identified 7 unique and literature-validated solubility tags and combined them with Expressioneering™ technology to create a suite of cloning-ready vectors for rapid and parallel evaluation of your protein with all 7 solubility tags (plus a 6xHis-tagged control vector).
Each pSOL vector contains everything you need to seamlessly clone in your target gene without any additional amino acids added. Fusion tags are cleavable via a TEV protease site.
Expresso Screening Workflow
Lucigen´s Expressioneering™ technology makes it simpler than ever to rapidly screen multiple fusion tags for solubility and expression enhancement. Use one amplicon to simultaneously create 8 different clones (7 fusion tags and one His-tagged control), followed by screening for solubility and expression.
Every protein reacts differently to various fusion tags. With the Expresso Solubility and Expression Screening System, you can quickly and easily screen multiple, proven fusion tags to find the optimal tag for your protein.
GH1 (Human Growth Hormone) was evaluated for E. coli expression and solubility when expressed as a fusion. Fusion tags SlyD, Tsf, SUMO, Bla, and MBP demonstrated enhanced solubility (Lane S) compared to teh His-control protein. T: Total Lysate, S: Cleared Soluble Fraction, I: Insoluble Pellet
Fusion Tags Included
The Expresso Solubility and Expression Screening System includes 7 vectors that each contain a unique fusion tag and one His control vector. The fusion tags vary in sequence, size, and derivative.
