xMAP® microspheres (or beads) come in a variety of formats. MagPlex® Microspheres, for example, are 6.5 micron superparamagnetic beads that are dyed with up to three red and infrared fluorescent dyes, resulting in 500 distinctly colored bead sets and delivering data on up to 500 analytes per well.

Multiplexing biological assays reduces time to results, sample requirements, and costs compared to traditional methods. With an open architecture design, you can choose from an extensive menu of commercially available kits and design your own assays.
Microsphere Analysis
xMAP beads are internally color-coded microspheres with precise concentrations of multiple fluorescent dyes, yielding up to 500 distinctly colored bead sets.
xMAP microspheres can be coupled with target-specific molecules such as antigens, antibodies, oligonucleotides, enzyme substrate, receptors, etc. After an analyte in a sample is captured by this target-specific molecule, a fluorescent reporter molecule is introduced to complete the reaction on the surface of each microsphere.
The internal dyes on the microspheres are excited by the red laser or LED to identify the microsphere set. Then, a green laser or LED excites the fluorescent reporter dye.
Using these signals, each individual microsphere is identified, and the amount of target molecule bound to its surface is quantified.
How It Works
Approximately 10 surface carboxyl groups (COOH) cover the surface of each bead and serve as covalent attachments for capture ligands. A fluorescent reporter is coupled to a target molecule, enabling detection following capture on the microsphere’s surface.
Advantages and Benefits
- High-Throughput Testing and Analysis – Because each microsphere serves as an individual test, a large number of different assays can be performed and analyzed simultaneously.
- Versatility – A single xMAP system can perform assays using several different methods and chemistries, including nucleic acid hybridization, antigen-antibody binding, enzyme reactivity, receptor-ligand binding, and other protein interactions.
- Accuracy – xMAP Technology generates data and accurately quantifies the biological interactions being tested.
- Flexibility – Multiplexing supports a variety of applications ranging from life sciences research and clinical diagnostics to food safety and biodefense.
- Reproducibility – High-volume production of xMAP microspheres within a single lot delivers reduced variability that solid-phased flat arrays cannot provide.
