[Histonet] RE: DAP vs Hoescht
I must respectfully disagree.
I use Hoechst 33342 diluted to 0.1ug/ml for 10 minutes on a daily
basis with various aqueous mountants including Pro-Long Gold (I agree
with Gayle that it is a good one), Slow Fade, Vectashield,
Fluormount-G, Gelmount etc etc. Works like a charm, never a problem,
