For Protein Expressions
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.
Invitrogen™ MultiShot™ BL21(DE3) Chemically Competent E. coli Cells, 96-well plate
MultiShot BL21(DE3) Chemically Competent E. coli Cells enable high-throughput protein expression with compatibility for automated liquid handling. This ready-to-use format streamlines cloning and expression workflows using the reliable BL21(DE3) expression strain.
Invitrogen™ MultiShot™ BL21(DE3) Chemically Competent E. coli Cells, FlexPlate
MultiShot BL21(DE3) Chemically Competent E. coli Cells offer high-efficiency protein expression in a flexible 96-well format. Breakable into 8-well strips, it enables convenient, scalable workflows for recombinant protein production and parallel cloning experiments.
MilliporeSigma™ Novagen™ Rosetta™ Blue (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™ 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™ 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.
MilliporeSigma™ Novagen™ Rosetta™ 2(DE3)pLysS 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.
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.
Gibco™ FreeStyle™ CHO Expression Medium
Animal origin-free, chemically defined, protein-free medium
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™ Tuner™ DE3 pLysS Competent Cells
Tuner host strains are lacZY deletion mutants of BL21, which enable adjustable levels of protein expression throughout all cells in a culture. T7 lysozyme expression suppresses basal T7 expression.
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.
