The article provides an overview of the reagents, materials and equipment for enzymatic treatment in paper conservation. Amylase, protease, and lipase are discussed. Although the author revues North American (USA and Canada) experience, almost all of it is well suitable for Russian conservation labs. The focus is on the practical and not the theoretical part, but the article offers a list of English-language literature where the reader can find detailed discussion on some reagents and processes, their physical and chemical properties and application in the conservation field. The author provides information on popular in United States manufacturers and suppliers of some materials and reagents, gives advice on their choice, acquisition, and storage. The article mentions some important points for drawing up a conservation treatment plan: it should be taken in consideration that an enzyme treatment might alter the artifact’s original binding, and that the buffer solution’s pH will be influenced by the native pH of the artifact. The article lists various methods of enzyme treatment: bath, gel poultice, application with a brush or a cotton swab. Also, the author provides a brief information about a pre-packaged α-Amylase poultice system Albertina-Kompresse manufactured by the German laboratory Klug Conservation and offers some literature that gives its detailed description. In conclusion, a valuable online resource “AIC Wiki Conservation Catalogs” is introduced.
