Sf9 cells in Sf-900™ II SFM Gibco™

Gibco® Sf9 cells are commonly used to isolate and propagate recombinant baculoviral stocks and to produce recombinant proteins. Gibco® Sf9 cells are adapted to serum-free suspension culture in Gibco® Sf-900™ II SFM, which saves significant time and expense associated with the adaptation of cultures.

ElectroMAX™ DH5α-E Competent Cells Invitrogen™

ElectroMAX DH5α-E Competent Cells are derived from the DH5α strain and are suitable for transformation by electroporation. They may be used in procedures requiring high transformation efficiencies, such as generation of cDNA libraries or in transformations with limited input DNA.

Grace's Insect Medium, unsupplemented Gibco™

Grace's Insect Medium was originally designed for the growth of cells from the Australian Emperor Gum Moth, Antherea eucalypti. One supplemented, Grace's Unsupplemented Insect Medium is now widely used for the growth of Spodeptera frugiperda cells, Sf9 and Sf21.

Grace's Insect Medium, supplemented Gibco™

Grace's Insect Medium, Supplemented, was originally designed for the growth of cells from the Australian Emperor Gum Moth, Antherea eucalypti. Grace's Supplemented Insect Medium is now widely used for the growth of Spodeptera frugiperda cells, Sf9 and Sf21.

Grace's Insect Medium (2X), supplemented Gibco™

Grace's Supplemented Insect Medium was originally designed for the growth of cells from the Australian Emperor Gum Moth, Antherea eucalypti. Grace's Supplemented Insect Medium is now widely used for the growth of Spodeptera frugiperda cells, Sf9 and Sf21.

OmniMAX™ 2 T1R cells offer the highest transformation efficiency of any chemically competent cells in a One Shot® format, with >5...

High Five™ Cells in Express Five™ Medium Gibco™

High Five™ Cells (BTI-TN-5B1-4) are a clonal isolate derived from the parental Trichoplusia ni cell line (cabbage looper ovary) and are commonly used for the expression of recombinant proteins using the Baculovirus Expression Vector System (BEVS).

MultiShot™ FlexPlate Mach1™ T1R Competent Cells Invitrogen™

MultiShot FlexPlate Mach1 T1R chemically competent E. coli cells are cloning competent cells that are pre-aliquoted in a 96-well PCR plate to increase transformation productivity. The FlexPlate format can be divided down to any combination of 8-well segments for flexibility in transformation...

MultiShot™ TOP10 Chemically Competent E. coli Invitrogen™

MultiShot™ TOP10 Chemically Competent E. coli provide transformation efficiencies of >1 x 108 cfu/µg control plasmid DNA, and are suited for high-throughput transformations. MultiShot™ TOP10 Chemically Competent cells are packaged in five 96-well microtiter plates (15 µL aliquots) to simplify...

Sf9 Cells in Grace's Gibco™

Gibco® Sf9 cells are commonly used to isolate and propagate recombinant baculoviral stocks and to produce recombinant proteins. The cells originated at the USDA Insect Pathology Laboratory, from the parental IPLBSF-21 (Sf21) cell line, which was derived from the pupal ovarian tissue of the fall army...

FreeStyle™ F17 Expression Medium Gibco™

Gibco FreeStyle F17 Expression Medium is a chemically defined, protein-free, serum-free medium developed to support the growth and transfection of HEK293 cells in suspension. The addition of 4–8 mM L-glutamine or GlutaMAX supplement is required before use.

Expi293™ Met (–) Expression Medium Gibco™

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. The medium is part of the Expi293 platform for rapid, high-yield transient protein expression from...

One Shot™ MAX Efficiency™ DH5α-T1R Competent Cells Invitrogen™

One Shot MAX Efficiency DH5α-T1R Competent Cells are derived from the popular DH5α strain. DH5α-T1R carry the tonA genotype that confers resistance to T1 and T5 phage. T1 bacteriophage spread rapidly and lyse E. coli hosts, which are commonly used for cloning and library construction.

CD Hybridoma Medium Gibco™

CD Hybridoma Medium is an animal origin–free, chemically defined, protein-free medium specifically developed for the ability to support the growth of hybridomas for antibody production. Gibco® CD Hybridoma Medium features: • Ability to support suspension and stationary hybridomas and myelomas •...

293 F Cells, in CD 293 Gibco™

Gibco® 293-F cells were cloned from the original 293 cell line and adapted to Gibco® CD 293 Medium. The 293 cell line is a permanent line established from primary embryonic human kidney and transformed with sheared human adenovirus type 5 DNA.
