Challenges in the Detection of Metabolic Biomarkers Using a Multi Plex Assay
In the work we present to the 14th EBF Open Symposium, we show a 5 Plex method for the detection of metabolic biomarkers in human plasma was developed using the U-PLEX technology on the MSD platform.
The complexities surrounding this method were the establishment of endogenous QCs for each chosen biomarker and evaluating the potential use and need for buffer QCs vs matrix QCs where applicable. Additional challenges were faced while trying to ascertain a single minimum required dilution to enable accurate quantification of all biomarkers simultaneously, encompassing the different detection ranges and limits for each biomarker.
The method development focused on the challenges of balancing the detection of the 5 biomarkers; ensuring that each could be quantified within its own required range whilst maintaining a method that was fit for purpose for all 5 biomarkers. To enable this balance, the context of use for each biomarker was evaluated and the method adapted as required.
A fit for purpose method was established that met the requirements for the need and context of use. The method was used successfully in the quantification of human samples from a clinical study.
