dialysis membrane for low MW

[Denni Schnapp]

Hi Netters!

I am trying to purify a peptide of 4 kDa or less and am looking for
suitable dialysis tubing. Sigma is selling benzoylated tubing but
demand princely sums of money (56 quid per 10 feet). Does anyone
know of cheaper suppliers with european representatives?!

P.S. Is there really nobody who knows whether IPN virus (or other
small viruses) stick to eppendorf tubes?

Greetings from bonnie Scotland...
