Multiplexing Assays

Proteome Profiler antibody arrays

Proteome Profiler

Discover Proteome Profiler Antibody Arrays offering you a quick and inexpensive way to analyse multiple analytes in a simple assay. The simple two site sandwich assay principle allows investigation of up to 119 analytes in a single sample in only 5.5 hours. An economical tool for biomarker discovery and more. 

Luminex Assays

R&D Systems partnered with Luminex Corporation to create high-quality multiplexing assays you can trust. The kits are available in two formats, Luminex Discovery Assays and Luminex High Performance Assays, for simultaneously detecting and quantifying multiple target analytes in qualified complex sample types.

Meet Ella

Take your multianalyte detection to the next level with Ella. To ensure high-quality, Ella’s Simple PlexTM cartridges are developed using R&D Systems antibodies and with a built-in standard curve, to deliver the results you need with unparalleled workflow ease. Multiplex assay panels for Ella are fully validated so that any 8 analytes within a specified panel can be combined in a 32x8 multiplex cartridge. 

Consistent Performance. Reliable Results.


Our DuoSet ELISA development kits contain all the essential components needed to develop a sandwich ELISA to measure recombinant and natural proteins. DuoSet assays offer a cost-efficient alternative to buying separate antibodies and proteins and optimizing your own assay. Choose from a selection of over 1,000 single-analyte DuoSet ELISAs.

ELISPot Kits

Our highly sensitive, microplate-based ELISpot assays provide efficient, accurate detection of cytokine secreting cells. Kits are available for detection and enumeration of a single analyte or two analytes simultaneously. Complete ELISpot kits are ready-to-run and require no assay development or refinement.
