How does Luminex xMAP work?
Luminex xMap technology is a bead-based multiplexed immunoassay system in a microplate format. In an assay using the Luminex system, the beads are incubated with a sample. After washing, the beads are incubated with a mixture of biotinylated antibodies against all the targets.

What is xMAP technology?
xMAP® – The World’s Most Used Multiplexing Technology xMAP® Technology allows users to perform a wide range of protein- and nucleic acid-based multiplex assays, which can simultaneously detect up to 500 targets in a single run.
What is Luminex assay used for?
Luminex xMAP (Multi-Analyte Profiling) technology enables scientists to measure multiple proteins in a single well. This technology combines advanced fluidics, optics, and digital signal processing with innovated microsphere technology to deliver multiplexed assay capabilities.
How does the Luminex 200 work?
Beads are read on a dual-laser flow-based detection instrument, such as the Luminex 200™ or FlexMap® analyzer. One laser classifies the bead and determines the analyte that is being detected. In addition to flow-based analyzers, magnetic beads can be read using the Luminex MAGPIX® Analyzer.

Is Luminex an ELISA?
Enzyme-linked immunosorbent assay (ELISA) has long been the standard for quantitative analysis of metabolic hormones and cytokines. LUMINEX multiplex bead array assays were developed as cost- and time-effective alternatives to ELISA, but they are the only cost- and time-effective if they provide informative data.
Which methods xMAP technology uses for detection?
The most widely used approaches are based on the DDH, ligation assays or ASPE, but multiplex detection of bacteria may be performed as well using MBMI.
How long does a Luminex assay take?
about 30 mins to 1 hour
The increased bead count does not affect the kinetics of the multiplex immunoassay. It only increases the time needed to acquire results per sample. Generally, each Luminex assay takes about 30 mins to 1 hour to analyze a 96 well plate on the platform.

Luminex Assay Protocol
- Prepare all reagents as instructed.
- Add 50 µL of standard or sample* to each well.
- Add 50 µL of diluted Microparticle Cocktail to each well.
- Wash by removing the liquid from each well, filling with 100 µL Wash Buffer, and removing the liquid again.
