Z-domain of protein A scaffold protein anti-Human Insulin

CAT#: SZA-L233

This insulin specific binding protein (Z-domain of protein A) was investigated by an α-helix shuffling strategy. The primary scaffold protein was from a naive combinatorial library of the three-helix bundle Z domain derived from staphylococcal protein A. A hierarchical library was constructed through selective re-randomization of six amino acid positions in one of the two α-helices of the domain, making up the Taq DNA polymerase binding surface. After selections using monovalent phage display technology, second generation variants were identified having affinities for insulin as determined by biosensor technology. It's potential to be used in diagnostic, research and therapeutic applications.
