     I just recieved something from MSI (http://www.msifilters.com)
saying that Amersham had replaced its supplier and implied that that
its MAGNA membrane would give the same results as the the old Amersham
Hybond-N membranes.  But MSI has changed its manufacturing protocol
recently, and several netters noted problems with this switch.  It
changed its protocols due to a patent infringement lawsuit by Pall
corp, so pall may be the best source of a replacement since they
probably supplied Amersham and use the old protocol for manufacture. 
It was also posted on this newsgroup recently that they were a favored
supplier.
