Nuclear localization of SF-1 can be used to distinguish sex cord-stromal tumors (SCST) from non-sex cord-stromal tumors (e.g., borderline tumors, serous carcinomas, etc.) and is therefore useful in the differential diagnosis of these neoplasms. Antibodies to SF-1 should be run in a panel with other sex cord-stromal tumor markers, such as inhibin and calretinin. Subcellular localization: Nuclear
