Why Is Dna Eluted with Water?

In addition, DNA must be stored at –20°C when eluted with water since DNA may degrade in the absence of a buffering agent

buffering agent
A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. ...

. Elution with TE (10 mM Tris·Cl, 1 mM EDTA, pH 8.0) is possible, but not recommended because EDTA may inhibit subsequent enzymatic reactions.

Why is water used to elute DNA?

DNA is more stable at a slightly basic pH and will dissolve faster in a buffer. This is true even for DNA pellets. Water tends to have a low pH, as low as 4-5 and high molecular weight DNA may not completely rehydrate in the short time used for elution.

Can DNA be eluted with water?

Yes, water can be used to elute DNA from Monarch columns. For maximum elution efficiency, ensure the water is nuclease-free and the pH is between 7-8.5. ... If you will be storing the DNA long-term, we recommend using the supplied DNA elution buffer which contains 0.1mM EDTA.
