[Histonet] H pylori and Ventana instruments

[Truscott, Tom]

I haven't used HP, but have noticed this stippled effect especially when using 40X on the microscope and looking at slides labeled with an Ventana alk-phos kit. I seem to have solved the problem by making sure no trace of H2O is left on the slides. It helps after washing slides to run them thru a few changes of alcohol then one acetone and then a couple xylene before coverslipping. Ventana suggested the acetone step. Tom T

We use Ventana's HP antibody, and we do see some of the small, non-specific globs of stain, but the pathologists are comfortable differentiating between the true and false staining since they are familiar with this artefact.

Hi all,

Those of you using Ventana instrumentation, could you tell me what H pylori antibody you are using, and whether or not you are experiencing non-specific staining, or staining that looks specific but with a stippled effect. 

Thanks
