Would you be kind enough to provide that reference?  I am trying to use
Oligotex at the moment for a similar reason, but the beads are sometimes
difficult to recover quantitatively by centrifugation as they sometimes
don't make a nice tight pellet, even in siliconized tubes.  Seems to me
that magneto-tech may allow better recovery after procedures that involve
extensive washing.
Thanks in advance,

Gene Huh
