Spatial proteomics in three-dimensional intact specimens
A novel spatial technique, DISCO-MS, combines whole-organ/whole-organism clearing and imaging, deep-learning-based image analysis, robotic tissue extraction, and ultra-high-sensitivity mass spectrometry with the Bruker timsTOF instrument family. This combination enables DISCO-MS to perform unbiased proteome analysis of preclinical and clinical tissues from quantity-limited materials after unbiased imaging of entire specimens in 3D.
In this webinar, you will learn about a new experimental approach that combines whole tissue clearing, dia-PASEF®, and trapped ion mobility spectrometry (TIMS) mass spectrometry to analyze the spatial proteome of complex tissue structures. The webinar will detail how with this technique, researchers were able to:
- Analyze the proteome of preclinical and clinical tissues after identification of regions of interest using 3D imaging, followed by robotic tissue extraction
- Achieve early unbiased detection and characterization of subtle tissue perturbations across pathologies
- Benefit from the use of ultra-high sensitivity and robust timsTOF mass spectrometers
Key learning objectives
- Discover the new experimental approach that combines whole tissue clearing, dia-PASEF®, and TIMS mass spectrometers can be used to analyze the spatial proteome of complex tissue structures
- Understand how researchers were able to analyze the proteome of specific tissue regions following 3D imaging to enable robotic tissue extraction
- Learn about the unparalleled sensitivity and robustness the timsTOF platform offers with 4D-Proteomics™ which enables researchers to delve deeper into proteome analysis and gain greater insights
Presenter: Dr. Harsharan Singh Bhatia (Institute for Tissue Engineering and Regenerative Medicine (iTERM))
Dr. Harsharan Singh Bhatia is the Omics technologies team leader at the Institute for Tissue Engineering and Regenerative Medicine (iTERM), Helmholtz Munich. He completed his Ph.D. at the University of Freiburg, Germany, studying the neuroprotective role of dietary antioxidants. Bhatia worked as a postdoctoral researcher at UCLA, where he investigated the impact of dietary manipulations on rodent behavior. He later returned to the University of Freiburg to work as a research associate at the University Clinic, exploring epigenetic factors' regulation of microglial function. In 2017, Bhatia joined iTERM to study chronic neuroinflammation using DISCO tissue clearing and spatial-omics tools.
