Anisotropy Probes

Ursa BioScience™ offers a range of fluorescence anisotropy probes. Our probes can readily bind nanoparticles and proteins allowing the nanoparticle / protein size to be determined, segmental motions or the binding of small molecules / other proteins to be studied. Our probes have excited state fluorescence lifetimes around 20 ns, making them ideal for protein sizing studies and determining the size of small nanoparticles.

Ursa BioScience™ offers 5 different fluorescence anisotropy probes. Each probe has either slightly different water solubility’s, facilitating affinities for different types of nanoparticles / proteins, and/or slightly different fluorescence / photophysical properties, e.g. fundamental anisotropy, excitation and emission wavelength etc.

Our anisotropy probes are sold dry in mirco-vials and are simply reconstituted by adding water/MeOH/EtOH and/or buffer. One vial of our probe will typically allow for 10 particle sizing measurements to be undertaken, when further diluted into 3 cm3 volumes within an appropriate cuvette.

For optimum performance, probe vials should be stored at -2 to -8 °C when not being used. Probe solutions should be used after dilution.

Ursa BioScience™ also offers convenient particle sizing kits, with Ursa’s range of particle sizing probes already dispensed within plastic 1-1-4 cm cuvettes for easy, quick and no hassle use. Our Electrostatic Particle Sizing Kit™ contains all 5 electrostatic probes dispensed within 1-1-4 cm cuvettes for customers wishing to try the significant advantages of both our dyes and nanoparticle metrology approach.
