Tissue dessication with table salt

Posted on by

There is a new paper published by Elena Carrió and Josep A. Roselló online early in Molecular Ecology Resources that suggests salt dessication of leaves dehydrates and prevents decay at levels similar to that of silica gel, with similar PCR results.

Large-grain silica is probably still the best option, but this would come in really handy if you come across something interesting that you want to collect but don’t happen to have silica gel with you.

Here is the main figure (link to the paper below):

Thanks to Maggie Wagner from the TMO lab who found this paper and sent it around. Here is a link to the full article:

Silica gel: God’s gift to botanists

Another Rieseberg lab member was asking me this week about preserving plant tissues on silica gel for later DNA extraction, and this got me to thinking about the general idea. I thought I would make a post about it, since it’s a useful technique, even in the genomic age. A lot of you already know all about this, so apologies for preaching to the choir.

I put an extensive post on my own Research Blog, but here is the gist of it:
