Copycontrol Fosmid Library Production Kit
Description

Efficient and improved systems for constructing libraries of approximately 40 kb clones in both standard or high-throughput screening versions.

  • Prepare unbiased fosmid libraries with a complete kit, including GELase enzyme and MaxPlax Lambda Packaging Extracts
  • Stabilize clones with copy number control Optimize high-throughput end-sequencing results with CopyControl HTP Fosmid Library Production Kit

The CopyControl™ Fosmid Library Production Kits provide an efficient and improved method for constructing a library of approximately 40 kb clones. The CopyControl pCC1FOS™ Vector contains both the E. coli F-factor single-copy origin of replication and the inducible high-copy oriV. CopyControl Fosmid clones are typically grown at single copy to ensure insert stability and successful cloning of encoded and expressed toxic protein and unstable DNA sequences. The CopyControl Fosmid clones can then be induced up to 50 copies per cell immediately before DNA purification. This step greatly increases DNA yields, while maintaining the stability of the plasmid.

 

The CopyControl HTP Fosmid Library contains the pCC2FOS™ Vector which is designed to optimize end-sequencing results, especially in a high-throughput setting. The primer cassette, engineered in conjunction with Agencourt Bioscience Corporation, eliminates wasteful and expensive vector sequence reads by having the 3´ ends of the primer-annealing sites only three bases from the vector/insert junction. In addition, the seven-base sequence at the 3´ end of each primer was specifically designed to minimize mispriming to any contaminating E. coli DNA present after template purification.

 

The kit uses a strategy of cloning blunt-ended DNA fragments generated by random shearing of the DNA, to produce more complete and unbiased genomic libraries than can be obtained by partial restriction endonuclease digests. Genomic DNA is first sheared into approximately 40-kb fragments. The sheared DNA is end-repaired to generate blunt, 5´-phosphorylated ends and then size-selected by and recovered from a low-melting-point agarose gel. Finally, the size-selected DNA is ligated into the cloning-ready CopyControl pCC1FOS or pCC2FOS Vector, packaged using ultra-high efficiency MaxPlax™ Lambda Packaging Extracts (>109 pfu/µg DNA), included in the kit, and plated on the supplied TransforMax™ EPI300™ E. coli.

Specifications

Applications

  • Preparation of complete and unbiased fosmid libraries, from any biological sample, that can be maintained at single-copy number and induced to high-copy number as needed, using the CopyControl™ Autoinduction Solution.
  • Construction of metagenomic libraries from microbes present in environmental samples such as water and soil.
Benefits
  • CopyControl pCC1FOS and pCC2FOS Vectors are supplied Cloning-Ready: linearized, dephosphorylated, purified, and ready for ligation.
  • No need for partial restriction endonuclease digests or pulse field gel electrophoresis to prepare the genomic DNA for cloning.
  • Maximize high-throughput end-sequence results using the pCC2FOS Vector
  • Clones can be induced from single copy up to 50 copies per cell
  • Safely obtain higher DNA yields while maintaining the stability of single-copy-number clones.
  • High-efficiency lambda packaging eliminates background and false positives.
  • "Hands-off" autoinduction protocol is perfect for high-throughput applications.
  • Faster and easier than BAC cloning.
