To the "brainy" histo-people, I have a student doing a cresyl violet stain on some frozen (40um) brain sections. He has been doing this routinely for a couple of months, but his last run looks very odd. There appears to be an area on each section where there is no staining. At first glance I thought it was a fixation problem, but the unstained portion of the tissue is in a different area as you move from slice to slice (these are serial sections), He stains in a Copeland jar and assures me that his stain is well homogenized. Could this be some kind of moisture problem?
Thanks for your thoughts.
