Multiplexed Assay Platforms

Multiplexing or multiple analyte detection offers a broad picture of the cytokines involved in a certain biological process. The measurement of cytokines and other soluble factors is becoming increasingly important in the study and management of numerous diseases.

Instrumentation

Luminex xMAP200 &  MagPix
The bead-based assays follow the same principle as a sandwich immunoassay. Fluorescent beads are coated with antigen-specific antibodies. A mixture of coated beads is incubated with the sample. Analytes in the sample bind to the Ab coating the beads. A biotin-conjugated Ab mix is added, which binds to the analytes bound to the capture Ab. A fluorochrome binds the biotin conjugates. Our instruments differentiates the bead populations and calculates the analyte concentration in the samples being analysed

Providing a rapid, reliable, cost-effective and informative solution, the main benefits of multiple analyte detection are:

  • Reduced cost and labour by multiplexing
  • Requires less than 50 µl of sample
  • Shortened time-to-results by favourable reaction kinetics
  • Give faster, more reproducible results than ELISA
  • Flexible multiplexing in the range of 1 to 100 analytes meets the needs of a wide variety of applications such as protein expression profiling, focused gene expression profiling, autoimmune disease, genetic disease, molecular infectious disease, and HLA testing
