Naomi's Nucleant MD2-07
Naomi’s Nucleant has facilitated the crystallization of 14 proteins, the
highest number reported for any single nucleant. Many of these proteins
have proven difficult to crystallize and some of these, including
membrane proteins, have only been crystallized in the presence of
Naomi’s Nucleants are made from bio-glass material (CaO-P2O5-SiO2) and has a highly porous surface with cavities of similar sizes to proteins (see image right).
Examples of proteins crystallized in the presence of Naomi’s nucleants are:
- A multi drug resistance protein (a membrane protein).
- Modified cyclodextrine.
- Myosin binding protein C.
- Lobster shell, α crustacyanin.
- A-actinin - actin binding protein.
