Sensitive assay methods for tyrosinase are essential not only for the understanding the process of pigment production but also for the development of effective inhibitors of tyrosinase. To develop an efficient assay method, we applied thymol blue to reaction mixtures.

The use of a hydrophilic ionic liquid (IL), 1-butyl-3-methylimidazolium chloride (C(4)mimCl), as a salting-out phase separation agent to a water-tetrahydrofuran homogeneous system was studied for possible applications to novel aqueous biphasic extraction separation. The IL showed a salting-out phase-separation ability.
