RE: [Histonet] notch-1

From:"Sebree Linda A."

Hi Valeria,

I have tried 2 of Santa Cruz's NOTCH-1 abs with no success on FFPE
sections (#s 6014 and 9170) but they don't claim to work for this
application or not with my system, i.e. raised in goat.  The one my
researcher DIDN'T buy is the 6014-R (raised in rabbit) that might have
actually worked with my system.  At my researcher's insistence, I did a
1:5 dilution, 10" HIER in a pressure cooker and amplification of the
primary ab.  All I got was nicely delineated epithelial cells against a
nasty brown background but no differentiation between normal and
malignant prostate cells, which was the focus of his research.

Good luck!.
