http://en.wikipedia.org/wiki/Dimethyl_sulfoxide ^^^^^^ has some VERY interesting properties that i think will make the delivery of different (especially hydrophobic RCs) very easy indeed, as is has the ability to carry other molecules in it and has a VERY high fast absorption rate. some one with more chemistry smarts should look into it.
i've wondered about this same thing... they use hbpcd(?) or something like that, which does pretty much the same thing as DMSO i don't really know where to get hbpcd, though i haven't tried to find out as i don't have a need for it, but my lab has a bunch of DMSO
yaaaay! im smart. any data on how to prepare the solution? does 25inbome disslove easily? any links to prep steps?
