Immunoassays based on Luminex xMAP technology enable simultaneous detection and quantitation of multiple secreted proteins (cytokines, chemokines, growth factors, etc.) and have been invaluable for the comprehensive study of biological systems. This high-throughput technology produces results comparable to ELISA but with greater efficiency, speed and dynamic range.

Columbia Biosciences manufactures and sells a high intensity PE streptavidin conjugate specifically for the Luminex assay kit.
