Competent Cells
Invitrogen™ Tali™ Cell Cycle Kit
Convenient and accurate determination of the percentage of cells in each phase of the cell cycle
MilliporeSigma™ Novagen™ BL21 (DE3) pLysS Singles™ Competent Cells
BL21 strains are the most widely used hosts for protein expression from pET recombinants and have the advantage of being deficient in both lon and ompT proteases.
MilliporeSigma™ Novagen™ Origami™ B (DE3) pLysS Competent Cells
Origami B host strain derived from a lacZY mutant of BL21 to enable precise control of expression levels using IPTG. T7 lysozyme expression suppresses basal T7 expression.
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 Competent Cell Set
HMS174 strains provide the recA mutation in a K-12 background.
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™ BLR (DE3) pLysS Competent Cells
BLR is a recA derivative of BL21 that improves plasmid monomer yields and may help stabilize target plasmids containing repetitive sequences. T7 lysozyme expression suppresses basal T7 expression.
Invitrogen™ MAX Efficiency™ DH5αF'IQ Competent Cells
MAX Efficiency DH5αF'IQ Competent Cells are high transformation efficiency chemically competent cells prepared by a patented modification of the procedure of Hanahan. This strain is a derivative of the DH5α strain, sharing the same benefits.
Invitrogen™ MAX Efficiency™ DH10B Competent Cells
MAX Efficiency DH10B Competent Cells are highly efficient E. coli suitable for a variety of molecular biology applications. This strain is one of the most commonly used strains for everyday applications due to key strain features such as high transformation efficiency.
Invitrogen™ One Shot™ MAX Efficiency™ DH10B T1 Phage-Resistant Cells
One Shot MAX Efficiency DH10B T1 Phage-Resistant E. coli have all the benefits of the DH10B genotype, with the addition of the tonA (also known as fhuA) genotype for resistance to T1 and T5 phage infection.
Invitrogen™ MultiShot™ StripWell DH5α T1R Competent Cells
MultiShot StripWell DH5α T1R chemically competent E. coli cells are cloning competent cells packaged in a rack containing 12 strips of 8 tubes to increase productivity for medium-throughput bacterial transformations.
MilliporeSigma™ Novagen™ RosettaBlue™ (DE3)pLysS Competent Cells
RosettaBlue host strains combine high transformation efficiency with enhanced expression of eukaryotic proteins. T7 lysozyme expression suppresses basal T7 expression.
MilliporeSigma™ Novagen™ Veggie BL21 (DE3) Singles™ Competent Cells
Protease-deficient hosts (BL21) for protein expression; Manufactured free of animal-derived media and components
MilliporeSigma™ Novagen™ Rosetta™ 2 (DE3) 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™ Origami™ 2(DE3) Singles™ Competent Cells
Origami 2 strains have mutations in glutathione reducatase (gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation.
