The R-PLEX platform offers matched sets of antibodies and calibrators for a wide menu of biomarkers. The R-PLEX Human CD81 (EV) Antibody Set can be used with other MSD components (see "Recommended Components" tab below) to build assays that measure exosomes and other extracellular vesicles (EVs) with CD81 present on their outer surface.

The Product Inserts for R-PLEX Antibody Sets provide detailed instructions for building assays in several formats. The Datasheet for CD81 provides lot-specific information for the components (including calibrator stock concentrations), recommended sample types and dilution factors, and representative data for analytical performance. These items and other helpful documents can be found in the "Documentation" tab below.
