I hope we find out here over the next few days.. if we all compare
experiences we may glean something ;-) !

>Can you uv Xlink Nitrocellulose?

My Hybond booklet says that HybondC (Amersham's nc) may catch fire if
you try, so I never have.

I mostly bake my nylon filters (uncharged), but occasionally xlink
them if I only have one or two to do.  I've never noticed any
difference either way, results-wise.  I did come across a paper (but I
can't remember where, just now) that did find a difference between
fixing/baking and "no treatment" - "no treatment" worked, but the
other two worked much better.
