50 mM MOPS,
15% isopropanol (v/v);
0.15% Triton® X-100 (v/v)
pH 7.0;

It is a nice find. I'm gonna give it a try.

Thank you for publishing this paper. You have saved our money

If you have further tips on reusing the DNA spin column, please post them here?

We would love to know

Has anyone tried reusing RNA columns such as Qiagen's RNeasy column?

[phage434]

The reconstitution papers referenced here fail to describe the N3 buffer used in the Qiagen minipreps. The guanidine hydrochloride used in buffers N3 and PB are not described, although these are important to binding DNA to the column. See this page for the composition of these buffers:

You might want to look at the Qiagen patent, which is linked off of that page as well.

Thank you for the link, phage434.

Welcome back phage434.

thank you, labtek

Any different recommendations for the Sigma GenElute columns. They come with a special column prep solution which I am not sure if it's the same as the Qiagen solutions.

I am confused about the method exactly.

It says to soak in 1 M HCl then rinse in sterile distilled water and equilibriate with Buffer QBT.

When they say rinse do they really mean just rinse or fill the column and keep cetrifuging the water through?

Also same thing about equilibrate. What does that mean exactly.

does anybody know about buffers from Macherei-Nagel NucleoSpin Blood L, NucleoSpin Plant L columns?

fill the column and centrifuge to get rid of the water

I mentioned this to a TA of mine, and he said that 1.0 M NaOH would probably be just as good. I dunno, I have some OMEGA HiBind DNA mini-columns, I was wondering if it would be possible to use a different buffer to capture RNA instead?
