General description
This PCR system is an improvement of the Barnes Technology and shows good performance for the amplification of fragments longer than 20 kb.
The Expand 20 kbPLUS PCR System is composed of a special 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 be used for fragments produced by this kit.
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 50 kb, as determined with agarose gel electrophoresis.
The Expand 20 kbPLUS PCR System contains human control DNA and human control ß-globin primers which allow the amplification of a 23 kb fragment.
These reagents may serve as a control reaction but can also be used to test the quality of human template DNA ´s and/or the respective primer pairs.
T/A cloning can be applied.
For a standard 50 μl PCR, we recommend using 5 U of the enzyme blend.

During meiosis, pairing of homologous chromosomes and their synapsis are essential prerequisites for normal male gametogenesis. Even limited autosomal asynapsis often leads to spermatogenic impairment, the mechanism of which is not fully understood. The present study was aimed at deliberately
