Receptors for luteinizing hormone-releasing hormone.
Authors:L A Sternberger
Abstract:Antisera to luteinizing hormone-releasing hormone (LH-RH) confer on Araldite sections of occasional rat pituitaries moderate immunocytochemical staining to the large secretory granules of gonadotrophs. Treatment of the sections with LH-RH before anti-LH-RH yields strong staining in all animals, irrespective of presence or absence of staining without pretreatment. This enhancement of staining is specific for LH-RH and is a high affinity, saturable reaction. Staining with or without LH-RH pretreatment is absent when anti-LH-RH absorbed with insolubilized LH-RH is used. Staining is inhibited by carboxyterminally-deficient LH-RH, unaffected by aminoterminally deficient LH-RH.
