Hyperfolder yellow fluorescent protein (hfYFP) and its variants are fluorescent proteins with high chemical and thermal stability. They resist aggregation, withstand diverse chemical challenges and show promise in expansion and electron microscopies. The chloride resistance and uncanny stability in guanidinium of hfYFP enable fluorescence-guided protein purification under denaturing conditions.
