The R-PLEX platform offers both antibody sets and assays for a wide menu of biomarkers. The R-PLEX Human CA19-9 Assay has the essential components to build an assay that measures CA19-9 in a single analyte format. For information on multiplexing CA19-9 with other analytes, please see the R-PLEX Assay Designer or the R-PLEX Human CA19-9 Antibody Set.

The Product Insert for R-PLEX Assays provides detailed instructions for building a singleplex assay. The datasheet for CA19-9 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.
