MALDI mass spectrometry is a technology that allows molecular measurements to be taken directly from tissue surfaces at specified coordinates without requiring antibodies or specialized reagents. This technology is ideally suited to provide molecular information to support and augment pathological decision points. In these experiments, a trained pathologist annotates regions of interest, and mass spectra can be collected directly from those regions. The mass spectrum represents a profile of ions from molecules from discrete locations. This process, called histology-directed mass spectrometry, can be used to augment pathological decision points. By collecting mass spectra from tissues with known pathology, a machine learning classification model can be trained to classify spectra taken from regions of tissue with unknown pathological states.
In this webinar, we will discuss histology-directed MALDI mass spectrometry and how this workflow has been used to diagnose invasive melanoma. We will discuss important factors relevant to setting up a clinical assay, including quality control and quality assurance metrics. Finally, we will discuss the performance of our assay for the detection of melanoma from human skin biopsies.
