Please note: The dye decomposes at pH-levels greater 8.0. For reasons of stability, please make sure that the pH value of a solution of this product never drops below 7.0. The recommended pH for a solution of this product is 7.5.

The limited stability of labeled ATPγS and GTPγS nucleotides makes it impossible to keep stocks of them and to offer them as catalog products that are available immediately.
Therefore, any labeled ATPγS or GTPγS is freshly prepared per order. For this reason the price is higher than for stable nucleotide-dye conjugates which can be synthesized and kept in stock.
