DNA storage
Most protocols suggest using a Tris-EDTA buffer for DNA storage. However, the EDTA in such buffers will chelate the Mg2+ in the PCR buffer, the concentration of which is vital, and so may cause problems with the sensitivity and specificity of the reaction. For this reason DNA can be simply stored in distilled water.
