MAX Efficiency™ Stbl2™ Competent Cells Invitrogen™

MAX Efficiency® Stbl2™ Competent Cells are high-efficiency chemically competent cells specifically designed for cloning unstable inserts. In addition to recA1, a unique set of genetic markers allow for stable cloning of direct repeat and retroviral sequences and tandem array genes.

Sf-900™ II SFM Gibco™

Sf-900™ II SFM is a serum-free, protein-free insect cell culture medium optimized for the growth and maintenance of Spodoptera frugiperda (Sf9 and Sf21) cells and for large-scale production of recombinant proteins expressed using the baculovirus expression vector system (BEVS).

Sf-900™ II SFM Gibco™

Sf-900™ II SFM is a serum-free, protein-free insect cell culture medium optimized for the growth and maintenance of Spodoptera frugiperda (Sf9 and Sf21) cells and for large-scale production of recombinant proteins expressed using the baculovirus expression vector system (BEVS).

Sf-900™ Medium (1.3X) Gibco™

Sf-900™ SFM is a complete serum-free, low protein insect cell culture medium developed for the convenient and reproducible formation of 1% agarose overlays used for plaque assays of baculovirus in Spodoptera frugiperda (Sf9 and Sf21) cells. When used with Gibco® 4% Agarose Gel, Sf900™ SFM (1.

IPL-41 Insect Medium (1X) Gibco™

Gibco® IPL-41 Insect Medium was originally designed for the growth of Spodeptera frugiperda (Sf9) cells and the expression of recombinant Autographa Californica Nuclear Polyhedrosis Virus (rAcNPV) using the Baculovirus Expression Vector System (BEVS).

One Shot™ TOP10/P3 Chemically Competent E. coli Invitrogen™

TOP10/P3 E. coliallow high-quality plasmid preparation of pCDM8, pcDNA™1.1, or any other supF-containing vector. The strain features: • P3 plasmid for selection of supF-containing plasmids • Mutated endA1 gene for increased quality of plasmid DNA preparations

BL21 Star™ (DE3)pLysS One Shot™ Chemically Competent E. coli Invitrogen™

One Shot™ BL21 Star™ (DE3) pLysS E. coli are chemically competent cells designed for applications that require high-level expression of non-toxic recombinant proteins from high copy number, T7 promoter-based expression systems (e.g., pRSET T7 vectors).

BL21-AI™ One Shot™ Chemically Competent E. coli Invitrogen™

One Shot® BL21-AI™ E. coli are chemically competent cells designed for applications that require tight regulation and strong expression of toxic proteins from any T7 promoter-based expression systems. One Shot® BL21-AI™ Chemically Competent cells have a transformation efficiency of >1×108 cfu/ µg...

One Shot™ BL21(DE3)pLysS Chemically Competent E. coli Invitrogen™

BL21(DE3)pLysS cells are ideal for use with T7 promoter-based expression systems (e.g., pRSET, pCR™T7, and pET). BL21(DE3)pLysS E. coli carry both the DE3 lysogen and the plasmid pLysS. pLysS constitutively expresses low levels of T7 lysozyme, which reduces basal expression of recombinant genes by...

MultiShot™ FlexPlate OmniMAX™ 2 T1R Competent Cells Invitrogen™

MultiShot FlexPlate OmniMAX 2 T1R chemically competent E. coli cells are a superior strain of cloning competent cells that are pre-aliquoted in a 96-well PCR plate to increase transformation productivity.

One Shot™ Stbl3™ Chemically Competent E. coli Invitrogen™

One Shot® Stbl3™ Chemically Competent E. coli are designed especially for cloning direct repeats found in lentiviral expression vectors. Unlike TOP10 E. coli, these cells reduce the frequency of homologous recombination of long terminal repeats (LTRs) found in ViraPower™ Lentiviral Expression...

One Shot™ BL21(DE3) Chemically Competent E. coli Invitrogen™

One Shot® BL21(DE3) Chemically Competent E. coli are ideal for use with bacteriophage T7 promoter-based expression systems (e.g., pRSET, pCR™T7, and pET). BL21(DE3) cells carry the lambda DE3 lysogen. Recombinant proteins that are nontoxic to E.

One Shot™ BL21(DE3)pLysE Chemically Competent E. coli Invitrogen™

BL21(DE3)pLysE E. coli are ideal for use with T7 promoter-based expression vectors. Like BL21(DE3)pLysS E. coli, BL21(DE3)pLysE carry the lambda DE3 lysogen. In addition, BL21(DE3)pLysE cells contain the pLysE plasmid, which constitutively expresses T7 lysozyme.

293FT Cell Line Invitrogen™

The 293FT Cell line is ideal for generating high-titer lentivirus using the ViraPower™ Lentiviral Expression System. The 293FT Cell Line is a fast-growing, highly transfectable clonal isolate derived from human embryonal kidney cells transformed with the SV40 large T antigen.

Flp-In™-293 Cell Line Invitrogen™

Flp-In™ 293 cell line is designed for rapid generation of stable cell lines that ensure high level expression of your protein of interest from a Flp-In™ expression vector. These cells contain a single stably integrated FRT site at a transcriptionally active genomic locus.
