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
