[Histonet] non specific staining with HER2 CISH

[Barry Madigan]

With the HER2 CISH procedure from Invitrogen we are experiencing non
specific staining on breast specimens with DAB.

The staining appears to be mucinous exudate from tumour cells.

Just wondering if anyone else has also experienced this as well.

It certainly doesn't help with counting.
