Inflamed proteins: Tyrosine nitration is a covalent post-translational protein modification that represents a biomarker for inflammatory diseases. We introduce a novel method to detect nitrotyrosine in biological samples by chemoselective conversion into a fluorophore. We describe the applicability of this methodology to detect protein-bound nitrotyrosine by fluorescence microscopy in tissue sections and on Western blot membranes.
