凝血因子VII是一种维生素K依赖型的单链糖蛋白，其编码基因共含9个外显子，全长12.8kb，定位于染色体13q34。hFVII属于丝氨酸蛋白酶家族成员，由406个氨基酸残基组成，分子量为45.5kDa，经过翻译后修饰分子量可达50kDa。血浆提取FVII（pdFVII）主要以酶原的形式存在，当Arg152与Ile153之间的肽键断裂后，FVII由单肽链形式转变为双肽链形式，形成有活性的FVII（activedhumancoagulationfactorVII，hFVIIa）。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有大鼠凝血因子Ⅶ(FⅦ)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大鼠凝血因子Ⅶ(FⅦ)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 Rat FⅦ. 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 Rat FⅦ 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.
