Sample Preparation Guidelines

To prevent isomerization and maintain structural integrity during laboratory analysis, it is strictly recommended to prepare the sample solution immediately upon dissolution and mix it freshly prior to your assay.

Short-term Storage of Solutions: Any prepared stock or working solutions should be stored tightly sealed at -20°C. Under these cryogenic conditions, the solution remains stable and can generally be stored for approximately one week.
