Overprocessed tissues are overhardened and brittle, resulting from possessing been excessively dehydrated or excessively cleared. Overprocessing most commonly takes place when an inappropriate tissue processing program has become picked for that tissue remaining processed; As an example, when a little biopsy specimen has actually been subjected to a protocol with dehydration and clearing occasions superior suited to a bigger specimen. Generally speaking, a tissue need to expend no far more time than necessary inside the dehydrating and clearing remedies, specifically If your clearing Resolution is xylene which is known to overharden tissues in excess of A few other clearing methods.
(a) Modest biopsy specimens need shorter processing cycles than massive specimens. A small biopsy specimen are going to be overprocessed if a substantial specimen processing protocol is employed; a significant specimen is going to be underprocessed if a little biopsy specimen processing protocol is applied.
