Early detection of cancer is essential to reduce mobility and mortality. This project focuses on developing the Affimer technology as a tool that can be used to detect biomarkers in clinical samples, as well as, to develop new screening strategies to isolate Affimers capable of being used immunohistochemistry (IHC)-like applications. In order to achieve our goals, an Affimer phage display library was screened against recombinant VEGFR2 and HER2, as well as against paraformaldehyde fixed-cancer cells. In order to test the specificity and sensitivity, two different labeling systems were used; biotin and creating an Affimer-alkaline phosphatase fusion protein. Our current data showed a specific and sensitive detection of VEGFR-2 and HER2 in IHC applications when compared to the antibodies. In addition, performing phage display against cell lines identified 8 unique breast cancer cell line-specific Affimers. Further characterization of other HER family proteins in addition to the identified cancer-specific Affimers will be performed. Finally, different strategies to enhance the sensitivity of the reagents in IHC will be developed.
