NGSelect Ready-2-Load

NGSelect Ready-2-Load

Convenient Illumina sequencing of ready-to-load libraries (RTL)

NGSelect RTL is designed to achieve maximum speed, cost-efficiency and easy-of-use for customers with ready-to-load libraries (RTLs). Scientists can submit their ready libraries and receive their results within a few business days.  Through multiplexing and pooling of samples the efficiency and cost-effectiveness of an Illumina sequencing run is significantly increased.


Ready-to-sequence libraries provide distinct advantages for researchers who are performing Illumina next-generation sequencing frequently:

  • More affordability - cost-effectiveness for power users of NGS, especially through multiplexing options
  • Faster results - significant improvement in data delivery times
  • Decreased variability – from semi-automated processes and optimized use of Illumina flow cells

Highlights NGSelect RTL

  • Results within as little as five business days
  • Wide range of sequencing options: choose from different reads modes, read numbers, and delivery time options
  • Extensive expertise in sample handling: semi-automated processes and optimised use of Illumina flow cells
  • Sequencing workflows with ISO17025 accreditation
  • Sorting by Illumina Index read at no additional costs
  • Accurate determination of library concentration and appropriate sequencing dilution

NGSelect RTL offers extraordinary fast and reliable sequencing of ready-to-load libraries. Benefit from extensive expertise in sample handling, proprietary protocols, as well as professional Bio-IT analysis.
