If processed tissue isn't clear, it is probably going which the clearing action was inadequate. By rendering tissues clear, the clearing move also will make some modest tissues hard to see during the embedding and microtomy measures. To lessen this problem, a small amount of liquid eosin is often additional either into the formalin or, far more usually, to one of several ethanol answers.
