MesoScale
Discovery (MSD)
Assays
Understanding the abundance of a specific protein or set of proteins is one of the most basic measurements needed in pre-clinical and clinical research, whether you’re tracking a biomarker, profiling cytokines, or testing immunogenicity with ADA assays.
The MesoScale Discovery (MSD) platform can analyze a range of analytes in complex sample matrices, with low sample volume requirements and high consistency between runs. This combination makes the MSD platform ideal for high throughput multiplex protein quantitation as well as anti-drug antibody (ADA) assays. Additionally, Precision can develop and validate custom MSD panels, or run fully validated kits.

Advantages of MSD assays
MSD assays work on the same principle as ELISA assays, but use an electrochemiluminescent signal as the detection method and have the capability to measure multiple analytes in a single well.

At Precision, we use MSD assays when sample is limited or matrix effects are expected to complicate detection. The MSD platform offers several advantages over traditional ELISA:
- Multiplex up to 10 analytes
- Wider dynamic range
- Higher sensitivity
- Lower sample volume
- Less matrix interference

Our MSD capabilities
- Assay development or transfer, validation, and implementation
- Pre-built, validated MSD assay plates
- Support pre-clinical through phase 3 studies
- ISO/GCP/GLP/CAP/CLIA regulated assays
Integrating biomarker and clinical trial data
To help researchers understand and interpret biomarker assay data in the context of other assays as well as the clinical trial data, Precision provides the option to manage and analyze assay data using our proprietary QuartzBio Translational Informatics platform.
