β- ara- 2'- Deoxy- 2'- fluoro- nicotinamide adenine dinucleotide (ara-2'-F-NAD⁺)

ara-2'-F-NAD⁺ aliquots (freeze-dried or in solution) are sufficiently stable to be stored up to 7 days at room temperature. Nevertheless, we recommend that the compound should be stored in the freezer, for longer storage periods preferably in freeze-dried form (-20 degrees Celsius necessary, -80 degrees Celsius recommended).

Lyophilized or crystallized sodium salt. The free acid or other salt forms are available upon request. Equal concentrations of ara-2'-F-NAD+ can appear very different in volume due to sensitivity of the lyophilized form to humidity. The compound can even contract to small volume droplets. Normally the product is located in the conical bottom of the tube. Micromolar quantities are determined by UV at λ_max.
