Competent Cells
MilliporeSigma™ Novagen™ Veggie NovaBlue Singles™ Competent Cells
Produces high-quality plasmid DNA
MilliporeSigma™ Novagen™ Rosetta™ 2 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.
MilliporeSigma™ Novagen™ NovaBlue GigaSingles™ Competent Cells
NovaBlue GigaSingles™ Competent Cells produce greater than 1 x 10⁹ colonies/μg plasmid DNA for cloning applications requiring high-efficiency transformations.
MilliporeSigma™ Novagen™ Origami™ 2 Competent Cell Set
Origami 2 strains have mutations in glutathione reducatase (gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation.
MilliporeSigma™ Novagen™ HT96™ NovaBlue Competent Cells
High-efficiency competent cells predispensed in 96-well plate for high-throughput applications
MilliporeSigma™ Novagen™ Origami™ B 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™ Rosetta™ Competent Cells
Rosetta host strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. coli.
MilliporeSigma™ Novagen™ BL21(DE3) Singles™ Competent Cells
BL21(DE3) is a chemically competent E. coli cell suitable for transformation and high level protein expression using a T7 RNA polymerase-IPTG induction system.
MilliporeSigma™ Novagen™ BL21 Competent Cells
BL21 host strain is the most widely used host background and has the advantage of being deficient in both lon and ompT proteases.
MilliporeSigma™ Novagen™ HMS174 (DE3) Competent Cells
HMS174 strains provide high transformation efficiencies and the recA mutation in a K-12 background. Strain may stabilize certain target genes whose products may cause the loss of the DE3 prophage.
Invitrogen™ MultiShot™ FlexPlate TOP10 Competent Cells
MultiShot FlexPlate TOP10 chemically competent E. coli cells are cloning competent cells that are pre-aliquoted in a 96-well PCR plate to increase transformation productivity.
Invitrogen™ MultiShot™ FlexPlate OmniMAX™ 2 T1R Competent Cells
MultiShot FlexPlate OmniMAX 2 T1R chemically competent E. coli cells are a superior strain of cloning competent cells that are pre-aliquoted in a 96-well PCR plate to increase transformation productivity.
MilliporeSigma™ Novagen™ Tuner™ Competent Cells
Tuner host strains are lacZY deletion mutants of BL21, which enable adjustable levels of protein expression throughout all cells in a culture.
MilliporeSigma™ Novagen™ NovaBlue T1R Singles™ Competent Cells
Featuring T1 and T5 phage resistance
MilliporeSigma™ Novagen™ HMS174 Competent Cell Set
HMS174 strains provide the recA mutation in a K-12 background.
