Product Description
10 x 96-tube Racks MultiShot StripWell TOP10 Chemically CompetentE. colicells are ideal for high-efficiency cloning and plasmid propagation, achieving a transformation efficiency of >1 x 108cfu/μg with control plasmid DNA in StripWell format. These cloning competent cells are packaged in a rack containing 12 strips of 8 tubes to increase productivity for throughput bacterial transformations.
Versatile TOP10 cloning capabilitiesMultiShot StripWell TOP10 Chemically CompetentE. colicells are the laboratory workhorse for chemical transformations as they are compatible with a broad spectrum of DNA types for transformation. They allow stable replication of high-copy number plasmids and are the same competent cells that come with many of our cloning kits.
TOP10E. colicells are genetically similar to the DH10B strain and have been reported to be more resilient to stress conditions (osmotic shock and acidic pH stress). These cells carry mutations in the methylation-dependent restriction system (mcrA,mcrBC, andmrr), allowing cloning of both prokaryotic and eukaryotic genomic DNA, as well as efficient plasmid rescue from eukaryotic genomes. Similar to other DH strains, TOP10 cells containrecA1 andendA1 mutations that increase insert stability and improve the quality of plasmid DNA prepared from minipreps.
MultiShot StripWell TOP10 Chemically CompetentE. colicells offer:
• Transformation efficiencies of >1 x 108cfu/μg
•hsdR for efficient transformation of unmethylated DNA from PCR amplifications
•mcrA for efficient transformation of methylated DNA from genomic preparations
•lacZΔM15 for blue/white color screening of recombinant clones on plates containing either X-Gal or Bluo-Gal
•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 DNANote:TOP10 cells do not require IPTG to induce expression from thelacpromoter.
MultiShot StripWell flexible formatEach StripWell of eight connected tubes is designed with the same single-tube, single-use features as our One Shot format tubes. This format allows all steps of the transformation protocol, up to plating, to take place in the same tube, thereby saving time and reducing chance of 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.
StripWell tubes can be cut to permit transformations in a single tube, eliminating wasted aliquots and avoiding freeze-thaws that can result in reduced transformation efficiency.
Benefits of the MultiShot StripWell format include:
•Increased productivity—suitable for high throughput experimentation
•Maximal flexibility—transform as few as 1 tube or as many as 96 from the StripWell rack
•Familiar convenience—add DNA directly to cells, heat shock, and recover in the same tubeGenotypeF–mcrA Δ(mrr-hsdRMS-mcrBC) φ80lacZΔM15 ΔlacX74recA1araD139 Δ(ara-leu)7697galUgalK λ–rpsL(StrR)endA1nupGFind the strain and format that fits your needsMany otherE. colistrains and formats ofchemically competentandelectrocompetentcells are also available to meet specific transformation needs.
