Please note: For reasons of stability, please make sure that the pH value of a solution of this product never drops below 7.0. This can be achieved by dissolving the nucleotide in a buffer of your choice (50 - 100 mM, pH 7 - 10). Dissolve and adjust concentration photometrically.
When stored at -20 °C, product may hydrolyze, thereby forming GppNH2 at a rate of up to 1 % per month!
