ELISA, single molecule counting assays and multiplex immunoassays using Luminex

Consistent analyte detection and quantification requires reliable reagents, and not all biomarker kits are created equal. Our kits are rigorously tested using a range of verified methods to ensure optimized performance and lot-to-lot consistency. Providing the specificity, biological dynamic ranges, and sensitivity that you require, our versatile ELISAs, ultrasensitive SMC™ assays, and MILLIPLEX® multiplex assays using Luminex® xMAP® technology deliver consistent performance, lot after lot. See the difference by choosing a platform with our biomarker kits to confidently deliver reproducible results.


Choose the Protein Detection Platform That Best Meets Your Needs:

How to Cite Our Products in Your Paper

Ready to publish?
We’re happy you’ve used our products to help you move forward in your research!

Research and discovery can move very quickly, and to ensure that others can reproduce and build upon the work that you are about to publish, we want to help you cite our products properly.

How to Cite MILLIPLEX®, ELISA, RIA, or SMC™ Assay kits

  • If you’re based in the USA or Canada, state MilliporeSigma as the source of your assay
  • If you’re based anywhere in the world besides the USA or Canada, state Merck KGaA, Darmstadt, Germany, as the source of your assay
  • Include the Catalog Number
    • If you used a MILLIPLEX® kit, also list the analytes you used from the kit
  • Include the species of samples you used, and how you diluted your samples
