A new continuous spectrophotometric assay method for DOPA oxidase activity of tyrosinase.
J. Protein Chem. 22(5) , 473-80, (2003) 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 ... |

Incorporation of dyes into low density lipoprotein in the presence of non-ionic surfactants.
J. Pharm. Pharmacol. 41(12) , 858-60, (1989) The interaction of low density lipoprotein (LDL) with two model dyes in the presence or absence of non-ionic surfactants has been studied. The water soluble dye, thymol blue, only weakly interacts with LDL to cause slight increases in particle size and the in... |
