Competent Cells
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.
Thermo Scientific™ DH10B Competent Cells; High Efficiency
High efficiency, chemically competent E. coli cells. The DH10B strain is suitable for cloning DNA containing methylcytosine, 5-hydroxymethylcytosine, and methyladenine, allowing both prokaryotic and eukaryotic genomic DNA to be cloned efficiently.
Thermo Scientific™ BL21(DE3) Competent Cells
Suitable for the expression of non-toxic heterologous genes. The strain contains the lambda DE3 prophage that carries the gene for T7 RNA polymerase under control of a lacUV5 promoter, allowing expression of the T7 RNA polymerase to be induced with IPTG.
Invitrogen™ One Shot™ BL21(DE3) Chemically Competent E. coli
One Shot BL21(DE3) Chemically Competent E. coli cells are ideal for use with bacteriophage T7 promoter-based expression systems such as pRSET and pET.
MilliporeSigma™ Novagen™ Rosetta™ 2(DE3)pLacI Competent Cells
Rosetta strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. coli. Contains the pLacI plasmid producing extra Lac repressor.
Invitrogen™ One Shot™ BL21 Star™ (DE3) Chemically Competent E. coli
One Shot BL21 Star (DE3) Chemically Competent E. coli are designed for applications that require high-level expression of non-toxic recombinant proteins from low copy number, T7-promoter-based expression systems such as Champion pET vectors.
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™ 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™ 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.
Invitrogen™ Tali™ Cell Cycle Kit
Convenient and accurate determination of the percentage of cells in each phase of the cell cycle
Gibco™ FreeStyle™ CHO Expression Medium
Animal origin-free, chemically defined, protein-free medium
Invitrogen™ MultiShot™ Mach1™ T1R Chemically Competent E. coli Cells, 96-well plate
MultiShot Mach1™ T1R Chemically Competent E. coli Cells enable rapid, high-efficiency cloning in an automation-ready 96-well format. Fast-growing and phage-resistant, these cells support same-day transformation and streamlined high-throughput workflows.
MilliporeSigma™ Novagen™ BL21(DE3) pLysS Competent Cells
BL21 host strain that expresses T7 RNA polymerase and also encode T7 lysozyme that suppresses basal expression of toxic target proteins prior to induction.
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.
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.
