<DIV><FONT face=Arial size=2>Dear Michael Cosgrove and colleauges.
</FONT></DIV>
<DIV><FONT face=Arial size=2>There can not be a better answer
than that of BORRIES's one about the use of 12mm for the
Dna-complex. I just want to illuminate the fact that as higher
the concentration more iones (salt) one has to add to the solution</FONT></DIV>
<DIV><FONT face=Arial size=2>for ion suturaion (to minimize the polyelectrolite
effect) or as smaller the conc less salt needed, this may has
an</FONT></DIV>
<DIV><FONT face=Arial size=2>importance since some complexes may aggregate
at high salt!!</FONT></DIV>
<DIV><FONT face=Arial size=2>Best published it is in: </FONT></DIV>

<DIV><FONT face=Arial size=2>There are some Graph of I/S versus
concentration at different salt conc. all extrapolated to zero
conc.</FONT></DIV>
