Used in research and diagnostic applications targeting GPR64 (ADGRG2), a receptor implicated in male fertility and certain cancers. This reference antibody is particularly valuable for detecting and quantifying GPR64 expression in tissue samples and cell lines. It supports studies on reproductive biology, especially in understanding male infertility due to its role in efferent duct function. Additionally, it is employed in oncology research, as GPR64 has been associated with prostate and other cancers, aiding in the development of targeted therapies. The antibody is also utilized in immunoassays and immunohistochemistry to validate target engagement and support drug discovery efforts, especially in relation to GPCR-targeted biologics covered under the Facet patent portfolio.
