Bis-propargyl-PEG10

Description

The genesig® Dengue, Zika and Chikungunya Virus Multiplex kit is designed for the detection and differentiation of Dengue virus, Zika virus (ZIKV) and Chikungunya virus (CHIKV) only. Individual tests have been designed in the conserved regions of each virus such that all isolates and subtypes will be detected simultaneously in the same test. The Dengue component of the test will detect subtypes 1, 2, 3 and 4 but will not differentiate between them. A positive Dengue test results indicates that the sample has either one of these four subtypes.

The primers and probe sequences in this kit have 100% homology with a broad range of clinically relevant reference sequences based on a comprehensive bioinformatics analysis. They therefore have a very broad quantification profile.

Exceptional value for money
Rapid detection of all clinically relevant subtypes
Positive copy number standard curve for quantification
Highly specific detection profile
High priming efficiency
Broad dynamic detection range (>6 logs)
Sensitive to < 100 copies of target Accurate controls to confirm findings 150 reactions

Description

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)
