Phage microarray profiling of the humoral response to disease
View Patent ↗The present invention relates to compositions and methods for cancer diagnostics, including but not limited to, cancer markers. In particular, the present invention provides methods and compositions for phage microarray profiling of cancer (e.g., prostate, lung, or breast cancer). The present invention further provides novel markers useful for the diagnosis, characterization, and treatment of cancers.
