Cytometric Bead Arrays: RayPlex™

Quantitative Multiplex Bead Immunoassay

RayPlex™ Cytometric Bead Arrays enable high throughput multiplex protein detection in a wide variety of sample types with flow cytometry; thus, coupling the versatility of RayBiotech's vast antibody pair library with familiar, reliable flow cytometry methodology.

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.
