Today I learned what Davidson's fixative is! Thanks! Anyway, so it's a strong alcoholic formalin. The answer to your question is; yes. You need to be careful of overfixation, thus masking the epitope in question. From Dako: " Of the many pre-analytical variables which affect IHC and ISH

Re: [Histonet] formalin and shrinkage

I was taught at AFIP to expect shrinkage of 10%, in each dimension. So I guess that's 30% shrinkage overall? Shrinkage is partially caused by formalin crosslinking the proteins in fixation, and partially by dehydration. Maybe a little shrinkage in xylene too? From removal of fat in adipose tiss

[Histonet] Job in Chicago?

Anyone know whose lab is looking for a temp in Chicago? I've been contacted by a couple of temp agencies about an assignment in Chicago, but I've been enjoying working as an independent contractor for a while now. So if anyone is in Chicago, and your lab is the one looking for a temp, please fee

[Histonet] Running a histo lab without a histotech?

Hello histonetters! I am on assignment in a small hospital lab in the Heartland and they are staffed by only two people. One is a registered (ASCP) HT with 10 years of experience, and the other is a former phlebotomist being trained on the job from scratch , who has yet to take her accreditation

Re: [Histonet] what to do with a dead processor

IIRC, don't those paraffin reservoirs slide out? Maybe you could warm them up with a propane torch to get them out? Then put them in an oven or just use brute force and patience to chip the paraffin out? As to who would want it, I don't know? Is a replacement motherboard available? Seems like

Re: [Histonet] IHC turnaround time

Let me get this straight, Dawn. You are running "In by 12, out by 5." on IHCs and your pathologist is* complaining*? A 5 hour TAT is awesome! Most places I've worked (and I've seen a lot in 16 years as a traveling tech) have at least a 24 hour TAT for IHC. I've got to get a shirt to th

Re: [Histonet] formaline 40% with crystals at the bottom

Cover it loosely, and warm it up a little with a stir bar, under a hood. You should be able to tell the difference between alcoholic and aqueous formalin by smell. Why isn't it labelled? Sincerely,
