US Patent Issued to Rizer Biotech on May 19 for "Selective time-resolved fluorescence anisotropy with switchable states" (Swedish Inventors)

ALEXANDRIA, Va., May 19 -- United States Patent no. 12,631,561, issued on May 19, was assigned to Rizer Biotech AB (Sandhamnsg, Sweden).

"Selective time-resolved fluorescence anisotropy with switchable states" was invented by Ilaria Testa (Solna, Sweden) and Andrea Volpato (Solna, Sweden).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for measuring polarization and anisotropy of fluorophores comprises activating reversibly switchable fluorophores in a sample. The activating comprises applying of a first activation light pulse of a wavelength suitable for switching the reversibly switchable fluorophores into a long-lived photo-selected state. Polarization and anisotropy of the reversibly switchable fl...
