Luminex Core Laboratory

The versatile laboratory multianalyte profiling (LabMAP™) system developed by Luminex Corporation, located in Austin, Texas, is a flexible, easy-to-use protein analysis system that permits the simultaneous quantitative analysis of up to 100 different proteins, peptides, or RNA molecules in a single microtiter well. This multiplexing feature allows one to obtain a wealth of information using a minimum amount of sample. Multiplexing enables a comprehensive overview of complex biological systems and the inclusion of in-process controls. In addition, sample volume requirements are reduced and assay throughput is dramatically increased. Potential applications include:

  • Functional genomics
  • Validation of drug leads
  • Secondary screening
  • Absorption and distribution
  • Metabolism

With the Luminex suspension array system, you can:

  • Quantitate up to 100 protein targets from culture media, sera, and other matrices simultaneously
  • Automatically analyze up to 96 samples in 60 minutes (general format: 88 sample wells + 8 standard wells)
  • Dramatically increase the amount of useful data

Selected Luminex Partners

We use all commercially available assays. Millipore, R&D Systems, Bio-Rad, and Thermofisher offer a robust network of assays for many different species and sample types. The useful nature of being able to multiplex and customize markers enables advanced detection of useful biomarkers.

In addition, we have also acquired a Curiox laminar plate washer to utilize DA-Bead methods to save money and sample.

QuantiGene® Plex Assay (ThermoFisher)

The QuantiGene Plex Assay is a hybridization-based assay using the xMAP® Luminex® magnetic beads and performed on 96-well plates. The assay is based on DIRECT quantification of the RNA targets using xMAP Luminex beads for multiplexing of 3 to 80 RNA targets and branched DNA (bDNA) signal amplification technology. On the first day, the sample is lysed to release the RNAs, and incubated overnight with target specific probe sets panel. On the second day, the signal amplification tree is built via sequential hybridization of PreAmplifier (PreAmp), Amplifier (Amp) and Label Probe (LP). Each amplification unit gives a 400 x signal amplification. and there are six amplification units per target RNA copy leaning to a 2,400 x signal amplification per copy RNA. The signal is detected by adding SAPE substrate and using a Luminex instrument for the read-out.
