Assay Development Tools

MSD scientists have developed a suite of assay development tools that meet the highest standards for quality and performance required for even the most demanding of assay development needs. These tools include our new U-PLEX platform designed to make multiplex assay development easy and our MSD GOLD Products that conform to rigorous specifications for uniformity and precision.

As part of our ongoing commitment to helping our customers achieve their research goals, we also offer supporting services that range from custom conjugating and printing plates with customer’s materials to full assay development services.

For Research Use Only. Not for use in diagnostic procedures.


U-PLEX Platform

The U-PLEX technology allows you to create your own multiplex assays. Using two simple tools—a 10-spot U-PLEX plate and unique linkers—you can build custom multiplex panels for any combination of analytes.


Multiplex assays can be performed in three easy steps:

  1. COUPLE a biotinylated capture reagent to an MSD U-PLEX linker.
  2. COAT the U-PLEX plate with a mixture of up to 10 U-PLEX-coupled antibodies.
  3. COMPLETE the immunoassay and analyze the plate on an MSD instrument.
