A review of current multiplex immunoassay methods Abcam

Multiplex platforms can offer distinct advantages over singleplex assays. The need for lower sample input has been alluded to already; typically 2550 3 targets multiplex time test method test reagent 3 targets multiplex time test method test reagent181;L sample volume is required to test multiple markers compared with 100 3 targets multiplex time test method test reagent 3 targets multiplex time test method test reagent181;L per target required for ELISA. Additionally, multiplex platforms often provide a gain in assay dynamic range.ASTM D7979 - 19 Standard Test Method for Determination 1.2 The method detection limit (MDL) 2 and reporting range 3 for the target analytes are listed in Table 1. The target concentration for the reporting limit for this test method was 10 ng/L for most of the target analytes at the time of development.
