WebNov 10, 2024 · Optical Tweezers can also be useful to investigate the folding cooperativity in proteins with multiple domains. This feature is crucial in molecular biology, since a lower cooperative communication between the different domains of a protein could increase the population of partially folded proteins and consequently promote misfolding diseases. WebIn this study we expand the accessible dynamic range of single-molecule force spectroscopy by optical tweezers to the microsecond range by fast sampling. We are able to investigate a single molecule for up to 15 min and with 300-kHz bandwidth as the protein undergoes tens of millions of folding/unfolding transitions. Using equilibrium analysis ...
