Competent Cells
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.
Invitrogen™ ElectroMAX™ Stbl4™ Competent Cells
ElectroMAX Stbl4 Competent Cells are specifically designed for cloning unstable inserts. This strain is a derivative of Stbl2 cells (engineered from JM109/J5 strain).
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
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.
MilliporeSigma™ Novagen™ Rosetta-gami™ 2 (DE3) pLysS Competent Cells
Rosetta-Gami 2 host strains allows for enhanced disulfide bond formation and enhanced expression of eukaryotic proteins. 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™ Subcloning Efficiency™ DH5α Competent Cells
Subcloning Efficiency DH5α Competent Cells are a versatile, chemically competent strain for cloning that provides a transformation efficiency of >1 x 106 cfu/μg plasmid DNA.
Thermo Scientific™ DH5α Competent Cells
Chemically competent E. coli cells recommended for routine subcloning into plasmid vectors. Subcloning efficiency cells are not suitable for the generation of cDNA libraries.
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 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™ 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™ 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 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.
