The reason of glomerulonephritis disease is to deposit the anti-GBM auto antibody in the glomerular basement membrane. The type IV collagen is the main component of glomerular basement membrane that has α3 chain of type (IV) collagen of non-collagenous domain which contains N-terminal 7S domain, a triple helical collagenous domain and C-terminal non-collagenous glomerular domain (NC1). The amino terminal of α3 (IV) NC1 that induces the Experimental Autoimmuno Glomerulonephritis (EAG) in rat model has been identified. The recombinant rat α3 (IV) NC1 antigen has nine amino acid spans that are consistent with antibody or T cell epitope that induces in EAG. The research is carried out on the recombinant rat α3 (IV) NC1 production, purification, quantification, and characterization. The circulation of anti-GBM antibody in glomerular basement membrane can be measured by the ELISA assay. In addition, the recombinant rat antigen is secreted in HEK293 cell supernatant that is purified by Anti-FLAG M2 monoclonal IgG antibody affinity column and characterized and quantified by SDS-PAGE gel electrophoresis and Western blotting techniques.展开更多
目的了解A、B、AB型全血加入O型全血不同剂量后血型正反鉴定、抗-A、抗-B抗体效价、直接与间接抗人-IgG实验变化。方法完全随机抽取4℃保存24 h A、B、AB型全血分别60 m l,按不同比例加入O型抗-A、抗-B效价1∶64的全血9、12、15、18 m ...目的了解A、B、AB型全血加入O型全血不同剂量后血型正反鉴定、抗-A、抗-B抗体效价、直接与间接抗人-IgG实验变化。方法完全随机抽取4℃保存24 h A、B、AB型全血分别60 m l,按不同比例加入O型抗-A、抗-B效价1∶64的全血9、12、15、18 m l置入100 m l塑料血袋内混匀后,置37℃孵箱,间隔15 m in摇动1次。分别在1、2、4、8、12、24 h留取标本,做血型正反鉴定、抗-A、抗-B抗体效价、直接与间接抗人-IgG实验。结果不同型全血加入不同剂量O型全血,37℃不同时间血型正反鉴定相符;相对应抗-A、抗-B抗体效价逐渐下降到消失;直接与间接抗人-IgG实验的变化,以B型接受O型的反应最小,在接受600 m l直接与间接抗人-IgG均为阴性,800 m l同1 200 m l反应基本一致。A、AB型接受O型后直接与间接抗人-IgG反应基本一致,实验结果均为阳性。结论以B型接受O型的反应最小,在接受600 m l直接与间接抗人-IgG均为阴性。800 m l同1 200 m l反应基本一致,A、AB型直接与间接抗人-IgG均为阳性。原则上最好不输O型全血,从直接抗人-IgG实验分析,只要红细胞上存在不完全抗体,就一定会影响红细胞的寿命与质量。展开更多
