About xTAG Technology

xTAG® Technology uses a proprietary universal tag system that allows easy development and optimization of nucleic acid assays. xTAG Technology combined with Luminex instruments is a complete solution for mid-density arrays evaluating gene expression, genotypes, or miRNA.

xTAG Technology


The TAG portion of the name represents TAG technology. TAG technology constitutes the proprietary sequences designed by Luminex for nucleic acid applications.


The advantages of using xTAG Technology in your nucleic acid assays are:

  • Sequences have been optimized to minimize cross-hybridization, thus preventing cross-talk in multiplexed nucleic acid assays.
  • Only three bases are used (TAG), preventing hybridization with native sequences.
  • Isothermal hybridization prevents long experimental design and testing times as seen when you have to choose your own capture sequences.
