BacPower™ Guaranteed Package

Our BacPower™ Guaranteed Packages now offer a comprehensive panel of options for your target protein production in bacterial expression system with guaranteed protein amounts, purities, endotoxin levels and the option of producing tag-free proteins as well, to meet a variety of your protein production 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 packages start with our proprietary codon optimization service, followed by gene synthesis and subcloning, all the way through protein expression and purification using our bacterial expression system.  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 service yet competitive pricing, exclusively offered with our BacPower™ Guaranteed 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.
  • Regardless of the methods used, in all cases, final protein will be guaranteed to meet customer specifications, failing which, any charge to the customer will be waived.
