Anti-tyrosinase assay
This anti-tyrosinase assay evaluates how effectively a substance inhibits the enzyme tyrosinase, which is key in melanin production. Such assessments are important for developing skincare formulations to reduce hyperpigmentation, antioxidants in food preservation to prevent browning, and other applications in cosmetics, pharmaceuticals, and agriculture. Tyrosinase catalyzes the oxidation of L-tyrosine to colored intermediates (e.g., dopachrome), detectable at 475 nm. Inhibitors reduce the formation of these colored products, lowering absorbance. By comparing the sample’s absorbance to a negative control, the percentage of enzyme inhibition is calculated, indicating the anti-tyrosinase potential of the test substance.
