| 预期应用     ELISA法定量测定大鼠血清、血浆、细胞培养物上清或其它相关液体抗球蛋白抗体(TG-Ab)含量。   实验原理     本试剂盒应用双抗体夹心酶标免疫分析法测定标本中TG-Ab水平。用纯化的抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入TG-Ab、生物素化的抗大鼠TG-Ab抗体、HRP标记的亲和素,经过彻底洗涤后用底物TMB显色。TMB在过氧化物酶的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的TG-Ab呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),计算样品浓度。   Intended use     This immunoassay kit allows for the specific measurement of rat TG-Ab concentrations in cell culture supernates, serum, and plasma.   Test principle     This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for TG-Ab has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TG-Ab present is bound by the immobilized antibody. An enzyme-linked monoclonal antibody specific for TG-Ab is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TG-Ab bound in the initial step. The color development is stopped and the intensity of the color is measured. |
