人血浆Fn的纯化、抗体制备及法医学应用的研究

ISOLATION AND PURIFICATION OF HUMAN FIBRONECTIN,PREPARATION OF ANTISERA AND ITS PRACTICAL USE

本文用Gelatin－Senharose4B亲合层析法提纯人血浆Fn抗原，免疫家兔，收集抗血清，经过去Fn血浆制成的免疫固相吸附剂处理后，制备特异性抗人Fn血清。此抗血清1：200稀释，用于免疫组化PAP、DAB染色法，观察人头皮枪弹创、头皮挫裂创、腹部皮肤切创各4例创缘区Fn含量、分布变化的研究，能反映创线区Fn变化的规律，为法医学创伤的研究，进一步开展定量分析和定量测定，作了抗体准备。

The fibronectin was purified from human plasma by Gelatin-Sepharose 4B affinity chromatography. The rabbits were immunized with the fibronectin. the raw anti-fibronectin sera were absorbed bythe solid phase of the fibronectin free human serum. Then the specific anti-fibronectin sera were obtained. The fibronectins deposited on human bullet wounds, incised wounds as well as on blunt forceinJuries were demonst.ated by PAP immunohistochemical study using diluted anti-fibronectin serum.The results were quite sati factory.
