Although xylene is used widely as a clearing agent for tissue, processing it is a toxic reagent. Some laboratories prefer to use less-toxic alternatives such as isopropanol or other xylene substitutes. For this method to be successful, higher wax temperatures are required so that isopropanol can be eliminated from specimens during infiltration.
