RayPlex™ Multiplex Bead Arrays
Take advantage of multiplex bead array technology for solution-based high throughput protein detection using a standard flow cytometer.
What Are RayPlex™ Multiplex Bead Arrays?
RayPlex™ Bead Arrays are a sandwich immunoassay that uses a capture antibody immobilized on the bead to detect a target protein, and a fluorescently-labeled detection antibody to visualize the captured target protein. By using different combinations of microbead sizes and fluorophores, you can simultaneously analyze multiple target proteins.
RayPlex™ is compatible with most standard flow cytometers that are equipped with blue and red lasers capable of detecting fluorescence in the phycoerythrin (PE) and allophycocyanin (APC) channels, respectively.
Armed with the precision that comes with sandwich immunoassay technology and the measurement capabilities of cytometric bead arrays, you can discover more deeply and more quickly with RayPlex™.

How RayPlex™ Multiplex Bead Arrays Work
RayPlex™ fluorescent beads are pre-coated with capture antibodies.
- Incubate your sample with RayPlex™ beads. The proteins will bind to the corresponding capture antibody bead.
- Detect bound target by adding biotinylated detection antibodies.
- Wash away unbound protein and add PE-conjugated streptavidin.
- Analyze beads with a flow cytometer.
- Process and interpret the flow cytometry data.
Research Applications
We’ve seen the RayPlex Bead arrays used to address a large range of research questions. Here are a few of our favorite applications:
- High-throughput profiling of cytokine expression.
- Validation of semi-quantitative antibody array results.
- Identifying potential molecular targets for drug development.
- Identifying the molecular mechanisms of drug action.
- Identifying crucial factors involved in disease processes.
- Discovering biomarkers for disease management.
- Discovering expression patterns for molecular classification of diseases.
Features
- Save sample without sacrificing data. You can quantify up to 25 proteins with only 25 µl of sample.
- Get results faster with only 4 hours of processing time.
- Save money with an array that’s 5-10x more cost-effective than ELISA.
- Enjoy simple workflows with no specialized or dedicated equipment required (compatible with most flow cytometers).
- Customize to fit your needs by creating a custom array from our list of targets.
