乙型肝炎病毒大蛋白(HBV-LP)是乙型肝炎病毒(HBV)核心抗原与宿主细胞受体结合后形成的一种非结构蛋白,属于病毒包膜蛋白的一种,主要存在于完整病毒颗粒(Dane颗粒)及亚病毒颗粒表面。其结构包含大表面蛋白(LHBs)、中表面蛋白(MHBs)和小表面蛋白(SHBs),其中LHBs通过前S1结构域与肝细胞受体结合,介导病毒入侵。HBV-LP是反映病毒复制活跃程度的关键指标,与HBV DNA水平高度相关。病毒复制活跃时,HBV-LP分泌增加,提示传染性增强;抗病毒治疗后,其水平随病毒载量下降而降低。此外,HBV-LP还能通过激活细胞内信号通路,参与肝细胞损伤及肝癌发生,对评估疾病进展具有重要意义。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人乙型肝炎病毒大蛋白(HBV-LP)捕获抗体的微孔中,依次加入样本、标准品、生物素标记的检测抗体,HRP酶结合物,中间经过温育和洗涤,用底物TMB显色,TMB在过氧化物酶(HRP)的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样本中的人乙型肝炎病毒大蛋白(HBV-LP)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD值),计算样本浓度。
This kit employs the sandwich enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with a capture antibody specific to Human HBV-LP. Following this, the sample, standards, a biotin-conjugated detection antibody, and an HRP (horseradish peroxidase)-labeled conjugate are added sequentially to the wells. The procedure involves incubation and wash steps between each addition. For detection, TMB substrate is used. TMB yields a blue color in the presence of the peroxidase activity of HRP. The reaction is then stopped with an acid solution, which converts the blue color to a final yellow color. The intensity of the yellow color is directly proportional to the concentration of Human HBV-LP present in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader. Finally, the concentration of the target analyte in the sample is calculated based on the standard curve generated from the standards.
