A New Assay Screening Method Shows Therapeutic Promise for Treating Auto-Immune Disease

MALDI-TOF platform advancements and other drug discovery articles are part of the original research
published in the January issue of SLAS Discovery.

Oak Brook, IL (January 27, 2023) – The January 2023 issue of SLAS Discovery contains a collection of four full-length articles and one technical brief covering cancer research, high-throughput screening (HTS) assay development and other drug discovery exploration.

This month's featured article, "A high-throughput MALDI-TOF MS biochemical screen for small molecule inhibitors of the antigen aminopeptidase ERAP1," by Müller, et al, presents a newly developed matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) drug discovery assay for the endoplasmic reticulum aminopeptidase 1 (ERAP1). The dysregulation of ERAP1 has been associated with various auto-immune and auto-inflammatory diseases, making ERAP1 a high-profile target in drug discovery.

The research team behind this study utilized an existing ERAP1 RapidFire MS (RF MS) assay on which to base their MALDI-TOF assay, producing greater assay stability, reproducibility and robustness for the MALDI-TOF platform. When results were compared between the pre-established RF MS and the MALDI-TOF platforms, shorter sample cycle times, reduced reagent consumption and a lower tight-binding limit were all advantages of the MALDI-TOF platform.

Read this original research article to learn how the MALDI-TOF platform may detect other difficult targets, along with more research articles in the January issue of SLAS Discovery.
