Chilly Chloroform?

[Richard P. Grant]

We have a protocol which calls for 'pre-chilled' chloroform during a
(genomic) DNA extraction (the material for extraction is supposed to be at
'room temperature' after a 60C incubation).

I've never used CHCl3 cold - does anyone have any idea why one should??

(The method seems to work AOK with RT CHCl3 and the material placed on ice
for 5').

cheers,

R
