Broadening the Workflow for Synchrotron-Based X-Ray Fluorescence and X-Ray Absorption Spectroscopy Imaging of Low-Abundance Cellular Metals
Metals play an essential role in cellular homeostasis and are key components of several formulations currently used in the clinic. Synchrotron-based X-ray microscopy at submicron resolution is a powerful approach to map intracellular elemental distributions and to monitor how these patterns change u...

| description |
Metals play an essential role in cellular homeostasis and are key components of several formulations currently used in the clinic. Synchrotron-based X-ray microscopy at submicron resolution is a powerful approach to map intracellular elemental distributions and to monitor how these patterns change upon genetic or pharmacological perturbations. However, existing sample-preparation protocols often rely on costly and highly specialized equipment for vitrification and dehydration, limiting their widespread adoption. Here, we present an adapted plunge-freezing and freeze-drying workflow that enables the preparation of mammalian cell samples for X-ray fluorescence (XRF) and X-ray absorption spectroscopy (XAS) studies with submicron resolution in a cost-effective and versatile manner. Furthermore, we define acquisition parameters optimized for the reliable detection of low-abundance metals, such as endogenous iron. We anticipate that this accessible protocol will facilitate the broader implementation of synchrotron-based inner-shell spectromicroscopy in cell biology. |
