We have been performing BrdU staining on Dog tissue with a DAB chromogen.
Our hematoxylin nuclear stain has been leaving some areas of the slide with
what looks like precipitate. We have diluted the hematoxylin to 50% and
filtered it more than once. We also have used different products, and we
still get some of this dark blue precipitate. can anyone suggest a reason?
One of the hematoxylins is the same as what we use for our regular H & E
staining and our regular slides do not have any precipitate and turn out
beautiful. Thanks for your help
