作者采用改良免疫转印法以胸腺细胞核抽提物检测1000例风湿病患者血清抗核抗体,发现其中4例血中有一种新型核抗原-抗体系统。病人血清与胸腺细胞核抽提物孵育后,在分子量53、94、120KD 处有显色反应,与已知的抗核抗体,如抗Sm、抗 The authors used modified immunotransfer method to detect serum anti-nuclear antibodies in 1000 patients with rheumatoid arthritis by thymus nuclear extract, and found that there was a new type of nuclear antigen-antibody system in 4 of them. Patient serum and thymus nuclear extract after incubation, molecular weight 53,94,120 KD at a color reaction, and known anti-nuclear antibodies, such as anti-Sm, anti
