Assays for the Luminex platform are offered as High Performance Assays  or Discovery Assays . The Luminex High Performance Assays are fully validated panels with a focused selection of analytes. They are available as Configurable User Mix and Premixed options or as Fixed Panels. The Luminex Discovery Assays allow for the maximum number of analytes in a multiplex and is supplied as a premixed kit.

Magnetic Luminex High Performance Assays  are designed for use with the Luminex MAGPIX CCD Imager. Alternatively, kits can be used with the Luminex 200™ or FLEXMAP 3D, dual laser, flow-based sorting and detection platforms.

Analyte-specific antibodies are pre-coated onto color-coded microparticles. Microparticles, standards, and samples are pipetted into wells and the immobilized antibodies bind the analytes of interest. After washing away any unbound substances, a biotinylated antibody cocktail specific to the analytes of interest is added to each well. Following a wash to remove any unbound biotinylated antibody, Streptavidin-Phycoerythrin conjugate (Streptavidin-PE), which binds to the biotinylated detection antibodies, is added to each well. A final wash removes unbound Streptavidin-PE and the microparticles are resuspended in buffer and read using a Luminex analyzer. One laser is bead-specific and determines which analyte is being detected. A magnet in the analyzer captures and holds the superparaMagnetic microparticles in a monolayer. Two spectrally distinct Light Emitting Diodes (LEDs) illuminate the beads. One LED identifies the analyte that is being detected and the second LED determines the magnitude of the PE-derived signal, which is in direct proportion to the amount of analyte bound. Each well is imaged with a CCD camera. Kits can also be used with Luminex 100/200 or a FLEXMAP 3D dual laser, flow-based systems.
