Overview

D-Neopterin is a precursor of tetrahydrobiopterin and can be used as a biochemical marker indicative of cell proliferation. Elevated levels of D-Neopterin are correlated to immune system activation, malignant disease, allograft rejection, and viral infections. Additionally, D-Neopterin serves as a cofactor for pterin in biological systems.

Note
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.
