摘要

蛋白HC (α 1微球蛋白)和α -胰蛋白酶间抑制剂在不同人体组织中的存在进行了研究。胰蛋白酶抑制剂是一种由比库宁和两条重多肽链组成的复杂蛋白。蛋白HC和bikunin是从一个共同基因转录而来的。肥大细胞中检测到α -胰蛋白酶抑制剂间免疫反应性。比库宁的抗血清吸收可阻断阳性反应,表明肥大细胞仅含有比库宁。在皮肤、结肠、肺结缔组织弹性纤维和血管内部弹性层上显示HC蛋白免疫反应性。在睾丸中,精管基底膜与蛋白HC抗体反应积极。

Human protein HC (alpha 1-microglobulin) and inter-alpha-trypsin inhibitor in connective tissue.

The presence of protein HC (alpha 1-microglobulin) and inter-alpha-trypsin inhibitor was investigated in different human tissues. Inter-alpha-trypsin inhibitor is a complex protein composed of bikunin and two heavy polypeptide chains. Protein HC and bikunin are transcribed from a common gene. Inter-alpha-trypsin inhibitor immunoreactivity was detected in mast cells. The positive reaction could be blocked by antisera absorption with bikunin, indicating that mast cells contain only bikunin. Protein HC immunoreactivity was revealed on elastic fibres in connective tissue of skin, colon and lung, and on the internal elastic lamina of blood vessels. In the testis, the basement membrane of the seminiferous tubules reacted positively with protein HC antibodies.
