Competent Cells
MilliporeSigma™ Novagen™ Tuner™ Competent Cell Set
Tuner™ strains are lacZY deletion mutants of BL21 and enable adjustable levels of protein expression throughout all cells in a culture.
MilliporeSigma™ Novagen™ Rosetta-gami™ B Competent Cell Set
Rosetta-gami B strains combine the key features of BL21, Origami, and Rosetta to enhance the expression of eukaryotic proteins. Contains the pLacI plasmid producing extra Lac repressor.
MilliporeSigma™ Novagen™ Rosetta™ 2 (DE3) Singles Competent Cells
Novagen's Rosetta™ 2 host strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. Coli.

Rosetta host strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. coli.
MilliporeSigma™ Novagen™ Rosetta-gami™ 2 (DE3) Competent Cells
Rosetta-Gami 2 host strains allows for enhanced disulfide bond formation and enhanced expression of eukaryotic proteins that contain codons rarely used in E. coli.
MilliporeSigma™ Novagen™ Rosetta™ Blue Competent Cells
RosettaBlue host strains are NovaBlue derivatives that combine high transformation efficiency and with enhanced expression of eukaryotic proteins that contain codons rarely used in E. coli.
MilliporeSigma™ Novagen™ BL21 Competent Cell Set
BL21 is the most widely used host background and has the advantage of being deficient in both lon (1) and ompT proteases.
MilliporeSigma™ Novagen™ Origami™ B (DE3) Competent Cells
Origami B host strains carry the same mutations as the original Origami strain, except that they are derived from a lacZY mutant of BL21 to enable precise control of expression levels using IPTG.
MilliporeSigma™ Novagen™ Origami™ 2 (DE3) pLysS Competent Cells
Origami 2 strains have mutations in glutathione reducatase(gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation. T7 lysozyme expression suppresses basal T7 expression.
