Bethesda TaMADOR Meeting Dec. 1, 2022


Targeted Mass Spectrometric Assays in Diabetes and Obesity Research

Marriott Bethesda Downtown, MD
December 1, 2022


Multiplex quantification of protein/peptide hormones and biomarkers involved in obesity and diabetes will facilitate translational scientific research.  Unfortunately, most assays today rely exclusively on antibodies and often there are no widely accepted guidelines or standardized methods to determine the validity of these reagents. Furthermore, many recent publications have highlighted the limitations of many commercial antibodies including failure to detect the intended target. The rigor and reproducibility of many assays commonly used by researchers in the field of diabetes and obesity could be substantially improved applying Mass Spectrometry (MS) instead of relying only on antibodies. Within last decade, major improvements in instrumentation and data handling have made MS–based targeted proteomics a highly reproducible methodology for detecting and quantifying proteins and peptides.

The NIDDK recently funded several projects that aim to use targeted MS approaches for quantifying human plasma/serum proteins and peptides of main interest to the obesity and diabetes research community.

This meeting will focus on advances made by the TArgeted Mass spectrometry Assays for Diabetes and Obesity Research (TAMADOR) pseudo-consortium and possible future directions. This includes insulin, pro-insulin, c-peptide, glucagon, adiponectin, leptin, secretin, and GLP-1, to name a few.
