Luminescent-conjugated oligo- and polythiophenes (LCOs and LCPs) are valuable tools for optical imaging of a plethora of protein aggregates associated with amyloidoses. Here, we outline updated protocols for the application of the anionic pentameric LCO, p-FTAA, for staining and hyperspectral imaging of protein aggregates in a variety of settings such as in vitro formed amyloid fibrils, ex vivo tissue sections, and whole brain Drosophila.
