EXPAND LONG TEMPL.PCR SYST. 150 U

General description

Expand Long Template PCR System is an enzyme mix that contains thermostable Taq DNA Polymerase and a thermostable DNA polymerase with proofreading activity. This powerful polymerase mixture produces a high yield of PCR product from genomic DNA. Expand Long Template PCR System allows amplification of DNA fragments up to 20kb from human genomic DNA, and 40kb from λDNA.
The Expand Long Template PCR System copies DNA threefold more accurately than Taq DNA Polymerase.
Misincorporations cause Taq DNA polymerase to fall off the DNA strand. The 3′→ 5′ exonuclease activity of the proofreading polymerase reaction mix amplify DNA three times more accurately than Taq DNA polymerase alone.
Long PCR products require a special buffer and optimized protocol. This kit has three buffers for amplifying fragments from 0.5 to 9 kb, 9 to 12 kb, and larger than 12kb. For high template quality, use Roche′s High Pure Template Preparation Kit to prepare genomic DNA template.

Application

The main application of the Expand Long Template PCR System is the accurate amplification of very long target sequences, even from genomic DNA. Use this optimized enzyme blend and specially developed three-buffer set to generate PCR products from 5 to 20kb in length.
Choose 1^st generation Expand Long Template PCR System for long and accurate PCR reactions. Use this optimized enzyme blend and specially developed three-buffer set to generate PCR products from 5 to 20kb in length. Use the product for:

• PCR
• RT-PCR or long-range PCR
• Large-fragment amplification
• Genome mapping and sequencing
• Contig construction
• Characterization of cloned sequences in lambda phages or cosmids
• Rapid identification and cloning of complete genes from genomic DNA  or cDNA sequence as starting material

As economical alternative we recommend to update to 2^nd generation Expand Long Range, dNTPack.
For amplicon sizes of 20 to 35kb choose Expand 20kb^PLUS PCR System, dNTPack.

Features and Benefits

Expand Long Template PCR System is ideal for genome mapping and sequencing, contig construction, characterization of cloned sequences in lambda phages or cosmids, and eukaryotic-gene cloning and analysis.

• Amplify longer templates: This 3-buffer set amplifies products from 5 to 20kb.
• Achieve higher yields and 3-fold higher fidelity compared to Taq DNA Polymerase.
• Improve your PCR: Obtaining more full-length PCR product is ideal downstream.

Packaging

1 kit containing 4 components

Quality

Each lot is PCR function-tested using human genomic DNA and specific primers for a 9kb, 12kb, and 15kb fragment. The enzyme mix is tested for the absence of any contaminating activities, including endo- or exonucleases and nicking activity according to the current Quality Control procedures.
