Milliplex cytokine detection systems are sandwich immunoassays performed on unique fluorescent beads, which contain a precise distribution of two fluorescent dyes, and a specific cytokine capture antibody linked to its surface. The fluorescent bead sets are incubated with a biological sample. A biotinylated cytokine reporter antibody is then used to identify the captured cytokine bound to the specific fluorescent bead. The reaction is detected by adding a streptavidin-phycoerythrin conjugate to the reaction mixture and read in a Luminex 100 instrument.
