I wouldn't conjugate your secondary and using a labelled secondary will
always boost your signal strength. have you determined where your
background is coming from? Do it again with a) no antibodies, b) primary
only c) secondary only to tell where your problem is. If it is either of
your antibodies you could either titrate it or wash with high salt washes.

I always buy the reagents separately, gives you more control. Which
chromogen are you using? Alk phos, POD or fluorescent?
You could also try asking in sci.bio.immunocytochem it gets little enough
traffic and could do with some.
