BacPower™ Guaranteed Bacterial protein expression packages

Our BacPower™ Guaranteed Bacterial protein expression packages offer a comprehensive panel of options for your target protein production in an E. coli system with guaranteed protein amounts, purities, endotoxin levels and the option of producing tag-free proteins as well, to meet a variety of your research needs. You simply provide protein sequence and we will deliver the protein (tagged or tag-free) at the amount and purity that you specified. All BacPower™ guaranteed bacterial protein expression packages start with our proprietary codon optimization service, followed by gene synthesis and sub cloning, all the way through protein expression and purification using our bacterial protein expression system. If your target recombinant protein becomes insoluble in the inclusion body fraction, FoldArt™, our proprietary protein refolding technology will be applied to solubilize the protein at no extra cost to you. This service is also ideal for the production of high quality protein antigens for antibody production. In case we fail on either the amount or purity as specified, there is no charge to you whatsoever.

Place your order today to experience unprecedented, high quality services yet competitive pricing, offered with our all of our Bacterial protein expression packages.

Terms and Conditions

  • Protein sequences are subject to pre-project analysis.
  • Exclusions are applicable to membrane proteins, toxic proteins and for target proteins greater than 100kDa.
  • To increase the expression level of your protein, codon optimization using our proprietary, OptimumGene™ technology, will be performed during gene synthesis.
  • Insoluble proteins maybe subject to FoldArt™ technology, GenScript's proprietary protein refolding platform.
  • In all cases, final protein will be guaranteed to meet customer specifications, failing which, any charge to the customer will be waived.
