[Histonet] MYOD1

[Troutman, Kenneth A]

Hi Donna,

I had a time with this one as well.  I use Dako's antibody on the Leica Bondmax.  I run it at 1:50 using ER2 for 30 minutes.  I would be careful going any stronger on the dilution, I got quite a bit of background with a 1:40, the 1:50 stains clean but can be a little weak if you don't use a fresh cut slide.  I ultimately decided to go with the 1:50 because I could get cleaner, consistent staining with it.

An equivalent for this protocol would be an EDTA (High pH) retrieval in a pressure cooker for about 20 minutes with a 10 minute cool down.  Antibody incubation on the Bond protocol is 15 minutes.  I would recommend about 30 minutes on an open system or if you are doing it by hand.  If you are running this on a Ventana platform I would start with a CC1 standard and at least 40 minutes on the antibody incubation.  You may have to bump the retrieval time up to the extended.

Good luck!
