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.
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.
Invitrogen™ One Shot™ BL21(DE3)pLysS Chemically Competent E. coli
One Shot BL21(DE3)pLysS Chemically Competent E. coli cells are ideal for use with bacteriophage T7 promoter-based expression systems such as pRSET and pET.
Invitrogen™ One Shot™ PIR1 Chemically Competent E. coli
One Shot PIR1 Chemically Competent E. coli cells are for use with vectors that contain the R6Kγ origin of replication (e.g., pUni/V5-His-TOPO for recombination with an Echo cloning system).
Invitrogen™ BL21 Star™ (DE3)pLysS One Shot™ Chemically Competent E. coli
One Shot BL21 Star (DE3)pLysS Chemically Competent E. coli are cells designed for applications that require high-level expression of non-toxic recombinant proteins from low or high copy number vectors, such as pRSET and pET.
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.
Invitrogen™ TOP10 Electrocomp™ Kit
TOP10 Electrocomp E. coli cells are provided at a transformation efficiency of 1 x 1010 cfu/μg supercoiled DNA and are ideal for high-efficiency cloning and plasmid propagation.
MilliporeSigma™ Novagen™ HMS174 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™ 2 Competent Cell Set
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.
MilliporeSigma™ Novagen™ Origami™ 2 (DE3) Competent Cells
Origami 2 strains have mutations in glutathione reducatase (gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation.
MilliporeSigma™ Novagen™ Origami™ 2 (DE3) pLysS Competent Cells
Origami 2 strains have mutations in glutathione reducatase(gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation. T7 lysozyme expression suppresses basal T7 expression.
Invitrogen™ One Shot™ INVαF' Chemically Competent E. coli
One Shot INVαF' Chemically Competent E. coli are designed to stably replicate high-copy number plasmids.
MilliporeSigma™ Novagen™ DE3 Competent Cell Set
