Maloisel and Perbal claim that Dichloromethane can be substituted for
chloroform without adverse effects, in DNA extractions.
I was wondering if anyone else has tried this. Their data seems pretty good
and since the paper is 3 years old I was wondering why more people have not
made the switch. Are we just too set in our ways or is there another reason.
I just looked in the Sigma catalogue and PRICE could be the reason.
Chloroform $19.95 for 500 ml
Dichlorom. $$12.00 for 500 ml
But wait FISHER
ACS grade 1 Liter
Chloroform $30.55 (C298-1)
Dichloromethane $30.75 (D37-1) They listed as Methylene Chloride.
Just goes to show you need to check more than one distributor.
So then the question remains.
Why don't we use it?
I will compile the responses ( if any) in a few days.
