DescriptionFluorescence labeling reagent.
- 4-[2-(6,7-dimethoxy-4-methyl-3-oxo-3,4-dihydroquinoxalyl)ethyl]-1, 2,4- triazoline-3,5-dione
Reagent for fluorescence labeling of Vitamin D and assay of Vitamin D metabolites.
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
