Microwave processing has long been demonstrated to supply superior quality morphological effects, and many publications assert no destructive effect on protein antigenicity or immunohistochemical labeling. A former barrier towards the implementation of microwave processing—that microwave use inserted manual ways into a method that was presently automatic—is defeat now that prime and ongoing throughput automatic microwave-assisted tissue processors are commercially accessible. Controversy remains as as to if accelerated formalin fixation achieved with microwave assistance is akin to time-based mostly formalin fixation, particularly as it pertains to accomplishing prognostic/predictive ancillary tests; As an example, at time of composing, rules continue to endorse a minimum formalin fixation time of six h for breast biomarker studies and don't distinguish in between common or microwave-assisted formalin fixation and processing.
Regrettably, while, several processors out there that declare the opportunity to perform immediate tissue processing are basically Yet another type of conventional tissue processor using the identical 4 traditional processing reagents with classic processing setups, that have various reagent ways and will take considerable time to method tissue properly.
