Phosphorescence (µS) Probes

We offer a patent protected unique range of organic Phosphorescence Probes with microsecond (µS)  decay times (lifetimes).  We offer probes which are both highly water and sparingly water soluble for your every need: including phosphorescence based imaging; O₂ sensing; protein tumbling and segmental motion observation; as a transduction element for collisional sensing and as a sensitizer of Singlet Oxygen generation (¹O₂).

Our Phosphorescent Probes are sold dry and are simply reconstituted by adding water/MeOH/EtOH and/or buffer. One vial of our Phosphorescent Probe will typically allow for 10 measurements to be undertaken, when further diluted into 3 cm³ volumes within a 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.
