Exo-Resistant Random Hexamer
Protects from 3'=>5' exonuclease degradation and ensures efficient priming of DNA synthesis.
| Description: MCLAB´s Exo-Resistant Random Primer is a mixture of single-stranded random oligonucleotides. It can be used in many applications such as highly efficient random priming of various DNA synthesis reactions. The primer in this prodcut has two 3´-terminal phosphorothioate (PTO) modifications that are resistant to the 3´> 5´ exonuclease activity of proofreading DNA polymerases (1), like Klenow Fragment and phi29 DNA Polymerase. It also has 5´- and 3´-hydroxyl ends. The product is supplied in a ready-to-use, 20x concentrated aqueous solution. Application: - Strand displacement amplification of genomic DNA (2), plasmids and phage DNA (3). - DNA labeling by random primers (4-6). Concentration: 500 µM (1.1 µg/µl) Quality Control: Functionally tested for the efficient priming of DNA synthesis using phi29 DNA Polymerase. Reference: 1.
