The only problem is, I don't have any PEG : with a MW higher than the cutoff for the dialysis tubing (12-14kD). Can I : use polyvinyl alcohol instead (MW supposedly around 70kD)? Thanks. Louis, for cryin' out loud you are at BERKELEY. Get off your lab stool and start walking around. Meet your neighbors! You'd be surprised how many important contacts you can make this way and, heck, you might even learn something--I'd lend ya some if you were here :-) Good luck, and by the way, CalBiochem makes a 500,000 kD monster that they market as "Aquacide II" so be on the lookout for that as well. Happy trails, Steve Dahl
