General description

The Expand 20 kbPLUS PCR System is composed of an enzyme mix containing thermostable Taq DNA polymerase and Tgo DNA polymerase, a thermostable DNA polymerase with proofreading activity. This powerful polymerase mixture and associated buffer system is designed to give a high yield of PCR product when fragments longer than 20 kb need to be amplified.
T/A cloning can also be performed.
The kit has control human genomic DNA and a set of control primers for amplifying a 23kb fragment. This test can be used to test template DNA and primer pair performance.
Use 3.75 U for a standard 50μL PCR.
Each dNTPack contains 10mM additive-free sodium salt nucleotides as a ready-to-use mix.
To obtain long PCR products, first evaluate length and purity of the DNA template. Handling all genomic DNA templates with care. Genomic DNA template should be larger than 50kb, as determined with agarose gel electrophoresis.

Application

Choose Expand 20 kbPLUS PCR System when amplifying genomic DNA fragments up to 35 kb. Expand 20 kbPLUS PCR System features a specifically optimized buffer and enzyme-blend mixture to amplify extra-long pieces of DNA (over 20 kb). Control primers and DNA produce fragments of 23 kb in length.
  • PCR
  • RT-PCR
  • Large-fragment amplification

Features and Benefits

  • Go the limit: The buffer and enzyme-blend amplify products over 20kb DNA.
  • Easy PCR monitoring: Human genomic DNA and human control β-globin primers amplify a 23kb fragment.
  • Test template quality: Control reagents also test template quality and primer pair performance.
  • Cost-effective: Use the convenient premixed solution of PCR grade dNTPs.

Packaging

1 kit containing 7 components

Quality

Each lot of Expand 20kbPLUS PCR System is function-tested in PCR using human genomic DNA and specific primers for β-globin to amplify a 23kb fragment.

Unit Definition

Volume Activity: 5 U/μl
