E. coli expression system is the most widely used expression method. Advantages of E.coli expression system includes: clear genetic background and metabolic pathway, mature method for expression regulation and time-saving cell culture.
Service highlight: 1. Up to 95% soluble protein expression. 2. Multiple choices for vectors, E.coli strains, tags and Restriction Enzyme cutting sites. Vector bank for different target protein: pET series, pBAD series and pCold series. |
