Ive been doing some reading up on dNTPs from various manufacturers. Nearly all suggest a storage pH range of between 7-8. It makes sense that you do not want a pH that is too low as it would increase the likelihood of hydrolysis reactions causing the formation of dNMP.
However, why would pH above 8 causes issues with dNTP storage?
Secondly, if I wanted to stabilise dNTPs for storage at temperatures in the 20-30c range what would be the most suitable method for achieving this without suffering loss of performance?
