Advancing Molecular Diagnostics with
Revolutionary Technology

QIAGEN’s proprietary Modaplex technology powers our Modaplex System’s multiplexed, quantitative and cost-effective arrays. 

Modaplex technology can achieve very high levels of multiplexing of nucleic acid targets by combining the precision of quantitative PCR reactions with separation power of Capillary Electrophoresis. The Modaplex system integrates PCR, CE, fluidics, detection and analysis software to provide excellent sensitivity and quantitation for densely multiplexed targets.

The Modaplex system electrokinetically injects sampled molecules from the PCR reactions into the capillaries and runs electrophoresis in real-time. The labeled amplicons are separated by size and the dyes are excited one of two lasers within the system. 



Because the Modaplex instrument has the ability to identify and follow amplicons by size during the reaction, there is no need to use more than two dyes and there is no need for excessive peak deconvolution. 

The system requires only 5-20 ng total Nucleic Acid per reaction, so that an unprecedented amount of information can be obtained from a relatively small amount of biological sample. 

Enabling High Multiplex Assays

Modaplex technology has been demonstrated to multiplex up to 20 targets in a single sample. It provides a quantitative answer and allows for mixed DNA and RNA target reactions, or multi-modal assays.

Three Easy Automated Steps 

Modaplex technology performs three automated steps to achieve high multiplex qPCR:

  1. End-labeled PCR
  2. Injection to Capillary Electrophoresis
  3. Analysis providing a report of copy numbers (or Ct)
