- Antibody microarrays enable extensive protein expression profiling, and provide a valuable complement to DNA microarray-based gene expression profiling. In this study, we used DotScan (TM) antibody microarrays that contain antibodies against 82 different cell surface antigens, to determine phenotypic protein expression profiles for human B cell sub-populations. We then demonstrated that the B cell protein profile can be used to delineate the relationship between normal B cells and malignant counterparts. Principle component analysis showed that the lymphomas did not cluster with the normal memory B cells or germinal centre B cells, but they did cluster with germinal centre founder cells and naive B cells.

- Human antibodies directed towards functionally associated tumor antigens have great potentials as adjuvant treatment in cancer therapy. Here we describe an efficient subtractive approach to select single chain Fv (scFv) antibodies, specifically binding to unknown rapidly internalizing tumor-associated antigens (TAA) on human breast and pancreatic carcinoma cell lines. After re-engineering the scFv into intact IgG molecules, these fully human antibodies displayed individual binding profiles to TAAs on breast, pancreatic, colorectal and prostate carcinomas, while showing no reactivity to lymphomas. The ability of the selected antibodies to undergo receptor-mediated internalization was verified by confocal microscopy, thus proving our strategy to provide a unique set of human antibodies, potentially useful in immunotherapy.
