Exo-Resistant Random Primer

Thermo Scientific Exonuclease-Resistant Random Primer is a mixture of single-stranded random oligonucleotides used for highly efficient random priming of various DNA synthesis reactions. This primer has two 3'-terminal phosphorothioate (PTO) modifications that are resistant to the 3'→5' exonuclease activity of proofreading DNA polymerases, such as Klenow Fragment and phi29 DNA Polymerase. It also has 5'- and 3'-hydroxyl ends. The Exo-Resistant Random Primer is supplied as a ready-to-use, 20X concentrated aqueous solution.

Features
• 3'-terminal PTO modifications protect from 3'→5' exonuclease degradation and ensure efficient priming of DNA synthesis
• Product delivered in a ready-to-use format

Applications
• Strand displacement amplification of genomic DNA, plasmids, and phage DNA
• DNA labeling by random priming
