Bacterial Protein Expression Guaranteed Package

Bacterial Expression Systems

Bacterial protein expression systems are both the most common and the most economical means of protein expression available today. However, two major problems often prevent researchers from making full use of the systems' advantages:

1) The protein of interest cannot always be expressed using the specific vector/strain combination
2) The proteins expressed in bacterial system are sometimes insoluble

GenScript has developed BacPowerTM technologies to tackle hard-to-express and hard-to-dissolve proteins. BacPowerTM technology package includes systematic procedures for expression optimization, such as testing of expression vectors and bacterial strains, induction optimization, and refolding.
