X-Message-Number: 17291 Date: Thu, 16 Aug 2001 09:25:07 EDT From: Subject: Bozzoneti: O2 is bad! OK, it's a necessary evil. But when we want to generate more superoxide radicals (there might be some more H2O2 too) in a cell culture dish and cause accelerated telomere shortening, we use 40% O2 in the incubator. Unless you live in the Himalayas, you should try to use chemical means (CoQ10 or whatever) to make better use of less oxygen. -Bill Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=17291
