|Reactivity||Human, Mouse, Rat|
|Calculated MW||39670 Da|
|Other Names||Inhibin alpha chain, INHA|
|Target/Specificity||A synthetic peptide corresponding to residues near the N-terminus of human Inhibin alpha chain was used as an immunogen. 20/23 kDa bands consist of the mature alpha chain. 50/53 kDa bands are the entire proprotein.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Inhibin Alpha Antibody Chain is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins.|
|Tissue Location||Originally found in ovary (granulosa cells) and testis (Sertoli cells), but widely distributed in many tissues including brain and placenta. In adrenal cortex expression is limited to the zona reticularis and the innermost zona fasciculata in the normal gland, extending centripetally into the zona fasciculata in hyperplasia. Also found in adrenocortical tumors Also expressed in prostate epithelium of benign prostatic hyperplasia, in regions of basal cell hyperplasia and in nonmalignant regions of high grade prostate cancer. Only circulating inhibin B is found in male, whereas circulating inhibins A and B are found in female|

Inhibin alpha chain is a peptide hormone that inhibits the secretion of follitropin by the pituitary gland. Inhibins and activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition (1). Granulosa-cell tumors produce inhibin and since serum inhibin levels reflect the size of the tumor, measurements of inhibin can be used as a marker for primary as well as recurrent disease (2). In the malignant regions of tissue from men with high grade prostate cancer, the expression of the inhibin alpha-subunit gene is suppressed and was not detectable in poorly differentiated tumor cells. These results demonstrate that in contrast to ovarian granulosa cell tumors, inhibin alpha chain is not expressed in poorly differentiated prostate cancer (3).
