本研究从正常人血浆中提取了纤维凝集素(FN),以此纯品制备抗FN抗体,建立了测定FN的放射免疫方法。应用本方法测定40份正常成人血清标本,结果显示FN正常值在40～100μmol/L的范围之间。从而为深入研究与FN有关疾病的病因学建立了新的测试方法,为确定国人FN的正常水平奠定了基础。
In this study, fibronectin (FN) was extracted from normal human plasma to prepare anti-FN antibody, and a radioimmunoassay was established to determine FN. 40 normal adult serum samples were measured by this method. The results showed that the normal value of FN was in the range of 40-100 μmol / L. Therefore, a new test method was established for the further study of the etiology of FN-related diseases and laid the foundation for determining the normal level of FN in Chinese.
