Will try the Biocare product and see if the results improve for us also.

I don't recall using the Ventana H. pylori but I was using the CellMarque H. pylori for years. It would often have a lot of background as you describe. I run Ventana Benchmarks (XT and Ultra) and a Leica Bond. The slides I would run on the Benchmarks were usually cleaner than those run on the Bond but still not as clean as I would like. I finally switched over to BioCare's H. pylori after many complaints from my pathologists. It has been much cleaner on all of my IHC instruments. Actually, the ones I run on the Ultra are the cleanest I have ever seen. The slides run on the Bond may still have a little background but it is still much cleaner than the ones I used to run with the CellMarque antibody. One of my pathologists who used to complain about the excessive background now calls it his "go to" stain and is very happy with how crisp it is. The organisms stand out very nicely. BioCare will send you a free sample if you want to try it.

We have been using this antibody for several years now and have never really been happy with the quality. We have tried the recommended methods to "clean up" the stain and still we run into repeating the stain and/or complaints from the pathologists. We are considering using a different vendor but my concern is that my efforts will be a lateral move. Is anyone using a product that produces a clean stain or is this something inherent to this antibody? Are the pathologists happy with it and not just tolerating it?

I need p16 antibody but not sure which vendor provide reliable antibody. I'd appreciate any recommendation. I also need melanoma and prostate ca control blocks, I can exchange with the once I have.

In my opinion, the science behind these fixation recommendations is "weak" at best. In my own experience, I have seen no problem whatsoever going well past 72 hours of fixation. The majority of breast cases will show internal positive controls for ER and PR to validate that the tissue is satisfactory for testing. Remember, working with your pathologist(s) you can perform your own validation on-site for extended fixation time. The real culprit for poor ER, PR, and HER2 IHC results is "inadequate" fixation.

I am in a little bit of a pickle with the 6-72 hour rule for the fixation on breast tissue. Friday I am getting 2 breast cases in the afternoon and both will not have the required minimum 6 hour formalin fixation for my per diem to cut early Saturday morning. He will not be able to make it in again until Monday night. The tissue will be about 3-4 hours (this includes time on the processor) over the 72 hour maximum. Does anyone have any suggestions on what can be done? We are a one person show here.
