I know, I am using formaldehyde to crosslink DNA and proteins for IP.

I don't say, that this is not happening, but I question the relevance.
As I never got any problems with keeping the ethanol at room
temperature, it is not necessary for me, to change the procedure.
YMMV. Nevertheless I would be interested in results from testing it.
And it would also be interesting to know, how much alcohol is oxidized
to the aldehyde.
