Hi,
we just found a note on the ordered formaldehyde bottle, that it contains 
10% methanol. The technical support gave us the information that all 
formaldehyde solution contains methanol to prevent paraformaldehyde 
precipitation, even if it is not indicated (?). Will this methanol 
content have negative effect on RNA in formaldehyde/agarose gels, and we 
should find "real" 37% formaldehyde in water, with that nice white pellet 
in it?
Thanks,
Namik Kaya
