[Histonet] Cover glass

[Helen Fedor]

Hello, Our lab does IHC staining in house and have had zero problems with our Fisher brand cover slips until recently. We've tried both Fisher and Corning cover slips and what appears to be dust or imperfections in the glass are found on both brands. This is creating false positives for us, because when the positive staining is low it is difficult to impossible to tell the imperfections from the staining itself.

Any advice will be welcome.
