使用格克斯表达质粒和用于产生单特异性多克隆抗体MINREC 4的融合蛋白,将人I型皮质类固醇(盐皮质激素)受体的N-末端结构域的167个氨基酸片段与谷胱甘肽S-转移酶基因融合。免疫染色实验表明,MINREC 4特异性结合大鼠肾脏远端小管、唾液腺导管元件和远端结肠上皮中的I型受体。肾上腺切除术取消染色腮腺和结肠,并减少免疫反应性的下颌下腺。皮质酮或醛固酮的管理导致腮腺中的免疫染色的部分恢复,和染色的完整恢复到完整的水平,在颌下腺和结肠。这些结果表明,肾上腺皮质激素与I型受体的结合可能导致结合蛋白的组织特异性构象变化,MINREC 4抗体可用于研究这些作用。
A 167 amino acid fragment of the N-terminal domain of the human type I corticosteroid (mineralocorticoid) receptor was fused to the glutathioneS-transferase gene using the Gex expression plasmid and the fusion protein used to raise the monospecific polyclonal antibody, MINREC4. Immunostaining experiments showed that MINREC4 specifically bound type I receptor in the distal tubule of the kidney, the ductal elements of the salivary glands and the epithelium of the distal colon in the rat. Adrenalectomy abolished staining in the parotid and colon, and reduced immunoreactivity in the submandibular gland. Administration of corticosterone or aldosterone resulted in partial restoration of immunostaining in the parotid, and a complete restoration of staining to intact levels in the submandibular gland and colon. These results suggest that adrenocorticoid binding to the type I receptor may result in tissue specific conformational changes in the binding protein and that the MINREC4 antibody may be used to study these effects.
