CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999Subject: PEG MW vs. cryoprotectivity From: price {- at -} UCHICAGO {- dot -} EDU price {- at -} UCHICAGO {- dot -} EDU Date: 2007-12-04 We've been having a discussion in the lab about whether or not middle-sized PEGs such as 4000 can be expected to serve as cryoprotectants (and if not, why certain commercial kits are formulated the way they are). Can anybody shed some light / references on the question of the size of PEGs vs. their ability to help in freezing? thanks, Phoebe --------------------------------------------------------------------------------------------------------------------------- Phoebe A.
