Endy:dNTP stock solution

Each individual dNTP comes as 25 μmol in 100 mM solution. The lids are color-coded to each nucleic acid.

1. Dilute these in DI water to 2.5 mM to get four tubes of diluted dNTP, i.e., n*(1 μl dNTP + 39 μl water).
2. Combine these in equal amounts to yield a 10x solution for use in PCR.

I don't know if there's any advantage other than to minimize freeze-thaw cycles to keeping intermediate dilutions of individual dNTPs rather than combining them immediately into the 10x solution. Sean 17:50, 30 Aug 2005 (EDT)
