Competent Cells
Invitrogen™ MultiShot™ StripWell Mach1™ T1 Phage-Resistant Chemically Competent E. coli
MultiShot StripWell Mach1 T1R chemically competent E. coli cells are exceptionally fast-growing cloning competent cells packaged in a rack containing 12 strips of 8 tubes for increased productivity of bacterial transformations.
Invitrogen™ One Shot™ INVαF' Chemically Competent E. coli
One Shot INVαF' Chemically Competent E. coli are designed to stably replicate high-copy number plasmids.
Invitrogen™ TOP10F' Electrocomp™ Kit
TOP10F' Electrocomp Kit E. coli cells are identical to TOP10 cells, with the addition of an F' episome.
Invitrogen™ MC1061/P3 Chemically Competent E. coli
MC1061/P3 Chemically Competent E. coli are used for highly efficient transformations that require the P3 episome for selection and maintenance of vectors encoding the tyrosine tRNA suppressor (synthetic supF gene, such as pCDM8, pcDNA1.1, or any other supF-containing vector).
Invitrogen™ MultiShot™ TOP10 Chemically Competent E. coli
MultiShot TOP10 Chemically Competent E. coli cells are derived from DH10B and are one of the most popular laboratory strains.
Gibco™ Expi293™ Met (–) Expression Medium
Expi293 Met (–) Expression Medium is a cGMP-manufactured, chemically defined, serum-free, protein-free, animal origin-free, methionine-free medium for growth and transfection of Expi293F cells.
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™ Tuner™ DE3 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™ 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™ Rosetta™ (DE3) 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™ 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™ Rosetta™ 2(DE3)pLysS 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™ Rosetta-gami™ B (DE3) Competent Cells
Rosetta-gami B strains combine the key features of BL21, Origami, and Rosetta to enhance both the expression of eukaryotic proteins and the formation of target protein disulfide bonds.
MilliporeSigma™ Novagen™ RosettaBlue™ (DE3) 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.
