Solvent & Solubility
H2O : 50 mg/mL (426.80 mM; Need ultrasonic)
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* 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.

For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
A murine macrophage cell line (RAW264.7) is used throughout the study, RAW264.7 cells are induced by A. actinomycetemcomitans-lipopolysaccharide, cells are incubated with various concentrations of L-norvaline or DL-norvaline (0.01, 0.1, 1, 10 mM) and 10 μg of A. actinomycetemcomitans-lipopolysaccharide. In other experiments, cells are incubated with antimurine CD14 or antimurine toll-like receptor 2 and 4 antibody at room temperature for 1 h, washed three times, and then stimulated with 10 μg of A. actinomycetemcomitans-lipopolysaccharide. All experiments are repeated three times, each consisting of triplicate cultures[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
