More often than I would like to admit when I have seen this type of problem it has been that there is a solution out of place on the processor or the stainer. I would start there. Mike

We are having issues with our H&E stain. The nuclei are staining very blue to purple and the mucin is staining blue to purple-blue. It is difficult to see the nuclear detail. The mucin is obscuring things. We have not changed our process for staining or processing. The funny thing is that it is only in the Biopsy cases, and it is every few slides. The surgical cases are all right. We checked the alcohol and xylene for water, and there is not any. My tech changed out the stain and we are staining a new batch of slides. If anyone has any idea what is wrong, any help would be greatly appreciated. I have gone over our processes and nothing has changed. The reagents are the same, the staining times are the same, and the processing times are the same. We are using the Shandon Gemini stainer and VIP processor.
