Bacterial Expression Service

Although overexpression or gene knockout can tell you a lot about its function and/or alter cell activity from an application perspective, sometimes it is better to delete genes from the bacterial genome itself or to introduce new genes and mutations into the bacterial genome itself. Direct manipulation of the genome allows you to have more fine-grained control over protein expression and activity, thereby limiting the use of cellular resources required to produce large amounts of protein or high copy number plasmids. Whether you are studying the basic biology of bacterial genes or changing metabolic pathways to produce therapeutic compounds, CD BioSciences has a variety of methods for changing bacterial genomes. From recombination to CRISPR, this collection contains a variety of tools to help you use bacterial genomes for research.

Overall solution

  • Regular T7 expression

The T7 expression system can use the powerful phage T7 promoter for high-level expression. It is very suitable for the expression of soluble non-toxic recombinant protein in E. coli.

  • Competent cell expression

Competent cells optimized the protein expression of T7 promoter.

  • High-level protein expression
  • Bacterial culture

Culture of bacteria, such as Escherichia coli (E. coli), requires specific formulations of growth media for use in cloning, plasmid DNA preparation, and protein expression. CD BioSciences offer a selection of bacterial growth media for your specific application.

  • Bacterial scale-up expression

The expression level can then be expanded to 10 liters or more to produce the protein quality required by the customer.

  • Adjustable expression
