This short article is a short review of problems with working with 10% NBF coupled with tissue processing as being a combined method to check biomarkers as recognized by immunohistochemistry.
Despite the need to have for quality and performance, nonetheless, laboratories may settle for considerably less-than-great excellent and productiveness of tissue processing given that they have just developed to simply accept it as “typical” with time. “This is how Now we have generally performed it” would be the phrase I normally listen to within the laboratories. It isn't unusual for laboratories to continue to employ protocols which have not been reviewed or current around long intervals, in some cases, for decades.
