DBCO-PEG6-DBCO is a monodisperse click chemistry linker containing two terminal DBCO groups with hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

For rapid, sensitive and accurate screening of potential Tyrosinase inhibitors
Tyrosinase (EC 1.14.18.1) is a copper-binding enzyme that is expressed across a vast range of species ranging from bacteria and fungi to mammals. It is involved in two sequential reactions of the melanin synthesis pathway: first being the hydroxylation of a monophenol and second the conversion of an ortho-diphenol to a quinone. Quinone then undergoes a series of reactions including polymerization to form melanin.
Tyrosinase is of great interest to the agriculture industry since it causes browning of fruits, vegetable, and mushrooms, as well as to the cosmetic industry as it causes skin darkening. Development and screening of tyrosinase inhibitors, therefore, is very useful for conditions such as hyperpigmentation and melasma. Tyrosinase activity is significantly increased in melanoma. Therefore, the detection of tyrosinase activity could be promising as a specific diagnostic test for melanoma and may be useful in monitoring patient response to melanoma treatments.
This Tyrosinase Activity Assay Kit is a simple one-step, plate-based assay for the measurement of tyrosinase activity in biological samples. In this assay, tyrosinase catalyzes the conversion of a phenolic substrate to a Quinone intermediate, which reacts with the tyrosine enhancer forming a highly stable chromophore with absorbance at 520 nm. The assay can detect as low as 30 μU Tyrosinase in biological samples.
Highly reproducibility
Highly Sensitive Assay to Screen for Tyrosinase Activity
Stable formulation of ready to use Reaction Facilitator (tyrosinase)
