RayPlex™ Bead Arrays

Quantitative Multiplex Bead Immunoassay

RayPlex™ Bead Arrays enable high throughput multiplex protein detection in a wide variety of sample types with flow cytometry.

RayPlex™ utilizes the sandwich immunoassay principle, wherein a target protein is immobilized between a capture antibody on a microbead and a fluorescently-conjugated detection antibody. By using different combinations of microbead sizes and fluorophores, multiple target proteins are analyzed simultaneously. 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.

Features

  • Less sample, more data: up to 25 proteins can be quantified from only 25 µl or less of your precious sample
  • 4 hour processing time
  • 5-10x more cost-effective than ELISA
  • Compatible with most flow cytometers
  • No specialized or dedicated instrument(s) needed
  • Customizable – create your custom array from our list of targets
