Kunitz domains scaffold protein anti-Human TNFα (CAT#: SKD-L116)
The Kunitz domain that bound TNFα was isolated from the library using Phage display techonology. Kunitz domains are stable as standalone peptides, able to recognise specific protein structures, and also work as competitive protease inhibitors in their free form. After affinity maturation, Kunitz domains variants were identified having affinities for TNFα as determined by biosensor technology. It's potential to be used in diagnostic, research and therapeutic applications.
