Rosetta host strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. coli. T7 lysozyme expression suppresses basal T7 expression.
Rosetta-gami B strains combines the key features of BL21, Origami, and Rosetta to enhances the expression of eukaryotic proteins. T7 lysozyme expression suppresses basal T7 expression.
One Shot BL21 Star (DE3) Chemically Competent E. coli are designed for applications that require high-level expression of non-toxic recombinant proteins from low copy number, T7-promoter-based expression systems such as Champion pET vectors.
