[Histonet] RE: Cornflaking artifact

[WILLIAM DESALVO]

Long time and high volume user of the Sakura Tape. Check the Xylene drops. We coverslip thousands of slides daily and have seen no isssue with the tape lots. Our experience shows some cornflaking when the slide does not receive enough xylens to wet the slide properly.

Wonder if it is possible to be a change in some type of supply, either xylene or coverslipping film.  Something has changed but am at a loss as to what.

> You will also see the cornflaking if your tissue is lifting off of the slide at all.  We used to get this more often on hard, decal specimens than on other specimens.  We used the film to coverslip.  If you remove the film from the problem slides and recoverslip conventionally with extra mountant and glass coverslips, I'm sure you will not see the artifact.

> I am looking for help with "cornflaking" (tiny, brown dry spots under coverslip)artifact.  We have been using fresh xylene on our stainer and coverslipper, cleaned and wiped all containers dry before filling, tried different lots of coverslipping film and had service on our coverslipper to make sure it was functioning properly, including the xylene drip.  We continue to have this artifact and it is driving us crazy.  It is sporadic with no pattern of tissue type or placement on the slide.  Sometimes it lands on tissue other times not.  Most of the time when we remove the coverslip and re-coverslip it goes away (I am assuming because the acetone removes any minute amounts of water that may be present).  We just cannot figure out where the water is coming from.  Has anyone seen this artifact while using the drying step on the prisma stainer?  We just recently started using the drying on some slides and I am thinking maybe it is causing humidity???  I cannot say for a fact that our "cornflaking" started at the same time, but it is suspicious. HELP!!!!!
