Allows solution to penetrate or gain entry into the interior of the tissue. 2. Exp: Alcohol Zinc salts mercuric chloride WebMercuric chloride-based fixatives include Helly and Zenker's Solution. One disadvantage of mercury-containing fixatives is that sections must be cleared of mercury deposits before IHC staining. The main disadvantage of these mercury based fixatives is that they are highly toxic, corrosive, and they require special disposal procedures.
