Dear experienced molecular community,
I would like to ship a plant fruit during the winter months with the intention of extracting RNA from the tissue. The fruit will be growing on a tree, and will be severed from the branches immediately before shipping.
I'm turning to you for advice on how to ship this tissue without damaging the RNA. Should I:
A) let it freeze in the mail and not worry about it
Insulate the fruit from the cold during shipping, so that it maintains non-freezing temperatures
C) flash-freeze the fruit and store it on dry ice to preserve the RNA during transport (would this option be a problem if, after shipping, I want to chop up the fruit, weigh, and re-freeze it?)
This is essentially a question about RNA stability in in-tact plant tissues. Please help!
