NGS Adapters & Indexing Primers

DNA Oligos for Next Generation Sequencing Applications
The quality and purity of NGS adapters and indexing primers are critical for the success of every next generation sequencing project. Thanks to its vast experience in the area of oligonucleotide synthesis (which extends beyond 30 years) as well as next generation sequencing (for more than 10 years), Microsynth knows exactly what the key requirements are for NGS oligos. Therefore, by choosing Microsynth, you're guaranteed to be in good hands when requesting NGS oligos only, or equally when outsourcing your entire NGS project.

1.0 umol  IEX-HPLC 40 – 80 6 OD 3 - 5

Microsynth has established and validated a specific process for the preparation of NGS oligonucleotides, based on a rigorous HPLC purification procedure in which the elimination of cross-contamination is a top priority.

How to Order

Important: Please first contact us at Microsynth and request your offer (volume discounts are possible!)

Option 1: When ordering NGS primers, please proceed as follows:

  • Enter our webshop, click on DNA in the blue “DNA/RNA Synthesis” domain
  • Select either Normal Entry in order to type or copy/paste the desired sequence information etc. or alternatively select Upload Entry by using our convenient Excel Template (can be downloaded during ordering)
  • Follow the further instructions


Option 2: When ordering primers for Illumina amplicon sequencing, please proceed as follows:

  • Use the dedicated “Order Form_Illumina_AmpliconDeepSeq” (can be downloaded in the right column); in this context see also our application note “Amplicon Deep Sequencing”)
  • Specify now the locus-specific sequences for your first-step PCR primers and then select your desired indexed forward and reverse primers
  • Enter our webshop, click on DNA in the blue “DNA/RNA Synthesis” domain and then on Upload Entry
  • Follow the further instructions
