Used in research and diagnostic applications targeting prostate stem cell antigen (PSCA), this antibody serves as a reference tool for immunoassays, flow cytometry, and immunohistochemistry. It enables detection and quantification of PSCA expression in cell lines and tissue samples, particularly in studies related to prostate cancer and other PSCA-associated malignancies. Its high specificity makes it valuable for validating new anti-PSCA antibodies and evaluating PSCA-targeted therapies during drug development.
