Biodesix’ Nicholas Dupuis, Ph. D, Speaking at MSACL 3rd Annual Conference


Biodesix’ Nicholas Dupuis, Ph. D, Speaking at MSACL 3rd Annual Conference: “Active Control of MALDI TOF Mass Spectra Acquisition With Internal Standards for Improved Quantitative Serum Protein Profiles”

Salzburg, Austria…Nicholas Dupuis, Ph.D, of Biodesix®, Inc. is speaking today at the MSACL 3rd Annual Conference, where he is the chairperson of the Protein Quantitation track. Dupuis is a Senior Scientist at Biodesix, where he leads technology transfer and assay development for proteomic products using Biodesix’ proprietary mass spectrometry based assays.

Where: Papageno Hall, Salzburg Congress Center

When: 11:15 AM

Short Abstract:

Matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometry (MS) is a rapid, reproducible, and sensitive tool for measuring protein profiles in biological fluids. Profiling has many potential clinical applications, including diagnosis, predicting disease aggressiveness, and assessing differential therapeutic benefit for cancer patients. In this study we: 1) incorporate multiple internal standards to allow quantitative comparisons between samples and 2) use a proportional-integral-derivative (PID) control algorithm to optimize spectral quality during acquisition. This approach expands the potential applications of MALDI profiling, markedly enhances spectral quality, and reduces reliance on operator intervention during acquisition.
