In the field of cheap protein-extraction cellulose binding domains (CBD) have made themselfes a name. A lot of publications have been made, concerning a cheap strategy to capture a protein from the cell-lysis with a CBD-tag. Also enhanced segregation with CBD-tagged proteins have been observed. Here the idea is different, we want to take advantage of the binding capacity of the CBDs not only for purification reasons (it is still a benefit), but also as an immobilizing-protocol for our laccases.

To make a purification and immobilization-tag out of a protein domain, a lot you have to get through a lot of decisions and characterizations of what has been done.

Starting with the choice of CBD, we decided to take only cellulose binding domains and no protein domains of other carbohydrate binding protein domain families to stay comparable. Else, changing to a different binding material would make a greater difference, than using domains of the same family.
