Reuse spin column......Perhaps it is something to think about......

Come across this publication, "Regeneration of commercial nucleic acid extraction columns without the risk of carryover contamination" published at Biotechniques......

I should have come across this few years back when I did used a lot of spin column for my research..... and at least I should have tried the method myself when I wrote this here today......

Giving some thought (s) after reading this publication, wondering how many people had actually tried this out? And how successful and how reproducible is the method outlined?

And will you be taking the risk by re-using the spin column to reduce the cost over the precious sample (s)???
