RE: [Histonet] Re: Distilled water rinse versus tap water rinsing,a curious thing
My institution's tap water does not blue my hematoxylin counterstain
to my satisfaction so this is why I prefer to use a blueing reagent
for immunos. I like my hematoxylin counterstain for IHC to be *really
really* blue so I need a blueing solution beyond that of tap water to
accomplish that. In addition, when doing quantitation based on color
gradations I wanted to install some sort of quality control and
reproducibility in the counterstaining and I found that using a
commercial reagent was better for that. I found the ammonia water we
were using for paraffin H&Es to be very harsh on my frozens so now I
use the Scott's. If your tap water blues appropriately I would keep
using that it is much cheaper (aka free). Also as Gayle mentioned
there are many other cheaper sources of reagents similar to Scott's
which work just as well.
