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™ Stbl3™ Chemically Competent E. coli
One Shot Stbl3 Chemically Competent E. coli are designed for cloning direct repeats found in lentiviral expression vectors as these cells reduce the frequency of homologous recombination of direct repeats found in lentiviral vectors (ViraPower Lentiviral Expression kits) and other retroviral vectors (instability-prone HIV-based plasmids).
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.
Promotions are available
