If you are looking for a good alternative to enzyme-linked immunosorbent assays to efficiently and simultaneously measure different panels of analytes (chemokines, cytokines, phosphoproteins, growth factors, human immunoglobulins etc.) in a single microplate well, then multiplex bead assay is your choice.

Our Main Facility is equipped with a Bio-Rad Luminex Cytometric Bead Analyzer, which can perform up to 40 assays (each bead is infused with fluorescent dyes in different ratios allowing for emission of different amounts of photons depending upon the amount of binding) in a single well, increasing assay flexibility as it can be used to perform immunoassays, nucleic acid research, enzymatic research, and receptor-ligand studies.Table
