Modified Primers

Modified Primers

We offer a broad spectrum of modified primers (oligo modifications) incorporated into an oligonucleotide available as a 5′-, 3- and internal modification. Our modified primers (oligo modifications) are purified by:

  • Reverse Phase Column
  • Reverse Phase HPLC

and available in the following synthesis scales:

  • 0,04 µmol (standard synthesis scale; most popular)
  • 0,2 µmol (medium scale)
  • 1,0 µmol (large scale)

Specification for DNA Reverse Phase Column (RPC) modified primers:

  • Deprotected & purified
  • Recommended for methods like PCR, sequencing and hybridization
  • Delivered as solid
  • Modification allowed (see price list for available modifications purified by RPC)
  • Certificate of Analysis (CoA) follows
  • 100% Quality Controlled (QC) by MassSpec
  • To be kept frozen at -18 C
  • Average in-house turnover time: 3-5 working days
