Competent Cells
Invitrogen™ One Shot™ MAX Efficiency™ DH5α-T1R Competent Cells
One Shot MAX Efficiency DH5α-T1R Competent Cells are derived from the popular DH5α strain and carry the tonA (fhuA) mutation that confers resistance to T1 and T5 phage.
Invitrogen™ Tali™ Cell Cycle Kit
Convenient and accurate determination of the percentage of cells in each phase of the cell cycle
MilliporeSigma™ Novagen™ HT96™ BL21(DE3) Competent Cells
High-efficiency competent cells predispensed in 96-well plate for high-throughput applications
MilliporeSigma™ Novagen™ Rosetta-gami™ B 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™ 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.
Invitrogen™ MultiShot™ StripWell BL21 Star™ (DE3) Competent Cells
MultiShot StripWell BL21 Star (DE3) chemically competent E. coli cells are cloning competent cells designed for applications that require high-level expression of non-toxic recombinant proteins from low copy number, T7 promoter-based expression systems.
Promega Bacterial Strain JM109
Useful host for transformation of pGEM Vectors and production of ssDNA from M18 or phagemid vectors. JM109 is recA- and lacks the E. coli K restriction system. Can be used for blue/white screening.
Promega Bacterial Strain JM109(DE3)
Used for high-level expression of genes cloned into vectors for expression of sequence downstream from the T7 promoter, if the sequence contains a ribosomal binding site. No blue/white selection.
