MULTISHOT STRIPWELL DH5A T1R EA，C449601，Invitrogen

MultiShot StripWell DH5α T1^R chemically competent E. coli cells are cloning competent cells that are packaged in a rack containing 12 strips of 8 wells to increase productivity for medium-throughput bacterial transformations. MultiShot StripWell DH5α T1^R competent E. coli cells are derived from the popular DH5α strain, one of the most frequently used laboratory cloning strains. All of our T1^R 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.

Reliable DH5α T1^R cloning capabilities
The DH5α strain is the standard laboratory strain for chemical transformations as it is ideal for transformations of cloned unmethylated DNA. The DH5α T1^R strain is useful for many cloning applications and provides transformation efficiencies of >1 x 10⁸ cfu/µg with control plasmid DNA.

Key features of MultiShot StripWell DH5α T1^R Competent Cells include:
• hsdR for efficient transformation of unmethylated DNA from PCR amplifications
• lacZΔM15 for blue/white color screening of recombinant clones
• endA1 for cleaner preparations of DNA and better results in downstream applications due to the elimination of non-specific digestion by endonuclease I
• recA1 for reduced occurrence of non-specific recombination in cloned DNA
• tonA (fhuA) for T1 and T5 phage resistance

MultiShot StripWell format—flexible for no waste
Each StripWell of eight connected tubes is designed with the same single-tube, single-use features as our One Shot format tubes. This format allows for all steps of the transformation protocol, up to plating, to take place in the same tube, thereby saving time and preventing contamination. After addition of DNA, MultiShot StripWell competent cells can be transformed by heat-shock at 42°C using a water bath, all in the same tube.

The StripWell tubes can be cut to permit transformations in a single tube, eliminating wasted aliquots of cells and avoiding freeze-thaws that can result in reduced transformation efficiency.

Key features of the MultiShot StripWell format include:
• Increased productivity—for medium throughput experimentation
• Maximal flexibility—transform as few as 1 tube and as many as 96 from the StripWell rack
• Familiar convenience—no aliquotting, add DNA directly to cells, heat shock, and recover in the same tube
• Peace of mind—single-use transformation minimizes contamination
