title: Utility, reliability and reproducibility of immunoassay multiplex kits.
abstract: Multiplex technologies are becoming increasingly important in biomarker studies as they enable patterns of biomolecules to be examined, which provide a more comprehensive depiction of disease than individual biomarkers. They are crucial in deciphering these patterns, but it is essential that they are endorsed for reliability, reproducibility and precision. Here we outline the theoretical basis of a variety of multiplex technologies: Bead-based multiplex immunoassays (i.e. Cytometric Bead Arrays, Luminex™ and Bio-Plex Pro™), microtitre plate-based arrays (i.e. Mesoscale Discovery (MSD) and Quantsys BioSciences QPlex), Slide-based Arrays (i.e. FastQuant™) and reverse phase protein arrays. Their utility, reliability and reproducibility are discussed.
