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. The FlexPlate format can be divided down to any combination of 8-well segments for flexibility in transformation throughput.

All of our T1R strains have the tonA (fhuA) deletion in their 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. A resistant genotype offers added security to protect valuable clones and libraries. This is especially important for genome and sequencing centers where T1 phage infection would be catastrophic.

Abundance of colonies with OmniMAX 2 T1R cloning capabilities
MultiShot FlexPlate OmniMAX 2 T1R cells are an improved chemically competent E. coli cell line, perfect for use in all cloning applications, including Gateway cloning, and provide transformation efficiencies in the MultiShot FlexPlate format of >5 x 108 cfu/µg with control plasmid DNA. These cells also provide efficient transformation of highly methylated DNA, since OmniMAX 2 T1R cells lack the E. coli K-12 restriction systems (mcrA Δ(mrr hsdRMS-mcrBC)).

Key features of the MultiShot FlexPlate OmniMAX 2 T1R Competent Cells include:
Δ(ccdAB) for sensitivity to the toxic effects of the ccdB gene product, allowing negative selection of vectors containing the ccdB gene—ideal for transformation of Gateway and TOPO reactions
mcrA, mcrBC, mrr, and hsdRMS elimination of restriction systems to allow construction of more representative genomic constructs
tonA (fhuA) genotype to confer resistance to T1 and T5 phage
Highest transformation efficiency in FlexWell format (>5x108 cfu/µg control DNA)
endA1 for increased plasmid yield and quantity
recA1 for reduced occurrence of non-specific recombination in cloned DNA
lacZΔM15 for blue/white color screening of recombinant clones

MultiShot FlexWell format—increase transformation productivity
The FlexPlate is a 96-well PCR plate that can be used in automated liquid handling systems or divided into any combination of 8-well segments for flexibility in transformation throughput. Addition of DNA to the MultiShot FlexPlate Competent Cells can be done quickly with a multichannel pipet or a liquid handling system. After addition of DNA, the cells can be transformed efficiently by heat-shock using a water bath, heat block, or thermal cycler.

Key features of the MultiShot FlexPlate format include:
Increase throughput—compatible with automated liquid handling platforms
Flexible—transform in increments of 8 wells to entire 96-well plate
Convenient—competent cells pre-aliquoted into 96-well plate, ready for transformation
