While I now use Innovex's DAB Enhancer, I have in the past (5-6 years ago)
used Osmium.  I don't
reccomend it for safety reasons.  NiCl metods also work well (carefull it's
a carcinogen) but
I've opted for the commercial (pricy) route because of time constraints.  I
might add that most
of the antiboby suppliers sell various DAB enhancing solutions.

If you still want to use Osmium I have the method somewhere ........ and if
you'll send me your
fax # I will send it to you (may take a while as I'm not sure where I filed
