Thick histological samples are difficult to image without proper tissue clearing methods. Among these methods ethyl cinnamate (ECi)-based clearing preserves antigenicity and is compatible with immunofluorescent labeling. In contrast to many other clearing protocols, ECi-based clearing is fast and is done as a final step after standard immunofluorescent labeling protocols.
