General Description of Inhibin .
Inhibin is a dimeric glycoprotein hormone from the TGF-beta family made of alpha and beta subunits. This antibody recognizes the 32kDa alpha subunit of human inhibin. Inhibin alpha is expressed in a wide variety of human tissues, such as brain, prostate, adrenal, granulose cells of ovary, sertoli cells of testis and in fetoplacental unit.

Inhibin Information for Pathologists


Inhibin is a heterodimeric protein (with alpha and beta subunits) that inhibits or activates pituitary FSH secretion. Serum levels elevated (2x) in women with Down fetus. Positive staining - normal Sertoli cells (diffuse and strong), granulosa cells, prostate, brain, adrenal. Positive staining - disease

Common Uses By Pathologists:

Normal sertoli cells (diffuse and strong), granulosa cells, prostate, brain, and adrenal as well as Sex-cord stromal tumors, including Sertoli cell tumors, adrenocortical tumors, placental and gestational trophoblastic lesions, granular cell tumors of gallbladder and extrahepatic bile ducts (Am J Surg Pathol 2001;25:1200), and some carcinomas stain positive for Inhibin A. Primary ovarian carcinomas are usually negative for the protein.
