Boc fixation - Study guides, Class notes & Summaries

An example of an additive fixative is one that contains: CORRECT ANSWER-picric acid Microscopic examination of an H&E stained section fixed in formalin shows marked nuclear bubbling. One most often sees this artifact if the specimen is processed following: CORRECT ANSWER-incomplete fixation Microscopic evalution of H&E stained sections from a surgically removed small bowl specimen shows an absence of much of the epithelium in otherwise normal tissue. This most likely resulted from: CORRECT...

Microscopic examination of a PAS stained section reveals marked nonspecific staining. This could be caused by fixation in: - correct answers glutaraldehyde solution The pathologist is sure that urate crystals were present in a tissue biopsy and should therefore be present in the H&E stained section, but polarization of the tissue is negative.
