Abstract

Background: The ability to simultaneously measure multiple secreted proteins and the corresponding gene expression levels from a single sample is valuable for comprehensive analysis. Bottlenecks to traditional immunoassays and gene expression assays include large sample consumption, time consuming experimental procedures and complex data analysis.

Method and results: Here, we demonstrate two high-throughput assays measuring both messenger RNA (mRNA) expression and proteins in a single sample run on a Luminex platform. Human peripheral blood mononuclear cells (hPBMCs) were treated with lipopolysaccharide (LPS) and harvested at 24 and 72 h. Samples were assayed with the ProcartaPlex Human Immune Monitoring 65-plex Panel for protein and corresponding mRNA targets on a QuantiGene Human 80-plex Panel.

Conclusion: Multiplexing ProcartaPlex and QuantiGene Plex assays provide a broad survey of protein levels and gene expression networks.
