Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .

用链霉亲和素-生物素-过氧化物酶(Strept Avidin-Biotin-Peroxidase Complex， SABC)免疫组织化学方法，以抑制素α亚基单克隆抗体对正常雌性性成熟大鼠各组织的抑制素α亚基进行定位观察，结果显示：⑴大鼠心脏、肾、脾、淋巴、肾上腺、胰腺均呈阳性反应，表明存在抑制素α亚基；下丘脑、垂体、肝脏和肺组织呈阴性反应，表明其不存在抑制素α亚基；⑵与去卵巢大鼠相比，外源注射抑制素α（1～32）片段的大鼠其下丘脑和垂体出现阳性反应，说明抑制素α亚基能通过血脑屏障。
