D-Tyrosine-d4
Based on 1 Customer Validation
D-Tyrosine-d4 is the deuterium labeled D-Tyrosine (HY-Y0444). D-Tyrosine is the D-isomer of tyrosine. D-Tyrosine negatively regulates melanin synthesis by inhibiting tyrosinase activity. D-Tyrosine inhibits biofilm formation and trigger the self-dispersal of biofilms without suppressing bacterial growth.

Biological Activity
Description
In Vitro
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.
Application
1. This compound can be used as a tracer
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Solvent & Solubility
In Vitro:
DMSO : 1 mg/mL (5.40 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 0.1 mg/mL (0.54 mM; ultrasonic and warming and heat to 60°C)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Protocols

Aerobic Bacterial Batch Culture on Broth/Agar
Aerobic bacterial batch culture grows a closed inoculated population in broth or on agar without continuous medium replacement; growth readouts include turbidity/OD for total suspended biomass and colony-forming units for viable cells able to form colonies on agar. OD-based growth curves reflect light scattering by cells, but OD is instrument-, pathlength-, species-, cell-size-, and density-dependent, so OD should be calibrated or interpreted alongside viable counts when quantitative cell density is required.

Fungal Biofilm Culture
Fungal biofilm culture is an in vitro method for growing surface-attached fungal communities, most commonly Candida albicans, on abiotic substrates such as polystyrene wells, silicone elastomer, or polymethylmethacrylate; the assay models adhesion, proliferation, filamentation, extracellular-matrix-associated maturation, and dispersion. Biofilm output can be read by optical density at 600 nm for adherent biomass, XTT reduction for metabolic activity, CFU recovery for viable attached or dispersed cells, and microscopy for architecture.
