Reactive Tag Viscosity Probes

Ursa BioScience uniquely offers several of our Viscosity probes with reactive groups / tags for attachment to thiol groups of biomolecules via maleimide conjugation. The significant advantage of our approach is that our viscosity probes can uniquely be positioned at the surfaces of either biomolecules or interfaces, and can subsequently report on local viscosity through either fluorescence emission or time-resolved fluorescence lifetime measurements. 

All our probes are supplied dry and lyophilized in 5 mg quantities. Larger quantities can be available on request to Tech@UrsaBioScience.com
For optimum performance, probe vials should be stored at -2 to -8 C when not being used.

Probe solutions should be used after dilution.
