Cells were harvested by centrifugation (4200g, 4 °C, 20 min) and either processed for protein purification immediately or stored at -80 °C. Following periplasmic extraction, ELP was purified using an Inverse Transition Cycling protocol adapted from Hassouneh et al. Following purification, ELP was dialyzed into deionized water, lyophilized, and stored at -20 °C. Purity was assessed using SDS-PAGE followed by Coomassie (KI8) or silver (I90) staining. Our full protocol for purification of ELPs from periplasmic expression systems is available on protocols.io. Full gene and protein sequence information is provided in the Supporting Information (Table ).
