The R-PLEX platform offers both antibody sets and assays for a wide menu of biomarkers. The R-PLEX Human Aβ40 (4G8) Assay has the essential components to build an assay that measures Aβ40 (4G8) in a single analyte format. For information on multiplexing Aβ40 (4G8) with other analytes, please see the R-PLEX Assay Designer or the R-PLEX Aβ40 (4G8) Antibody Set.

The Product Insert for R-PLEX Assays provides detailed instructions for building a singleplex assay. The datasheet for Aβ40 (4G8) provides information on the components (including calibrator stock concentration), 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. The 4G8 antibody is supplied by BioLegend (previously from Covance Research Products).
