成纤维细胞生长因子 19(FGF19)是一种蛋白质，由 FGF19 基因编码。它作为 一种激素发挥作用，调节胆汁酸的合成，对葡萄糖和脂质代谢有影响。该基 因所编码的蛋白是成纤维细胞生长因子（FGF）家族的一个成员。该生长因 子是 FGFR4 的高亲和力、肝素依赖性配体。FGF19 也存在于胆汁淤积症患 者的肝脏中。它可以在胆囊中合成并分泌到胆汁中。它也在大约一半的肝细 胞癌中表达，并与体积较大、早期复发和预后不良有关。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有小鼠成纤维细胞生长因子19(FGF19)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小鼠成纤维细胞生长因子19(FGF19)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 Mouse FGF19. 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 Mouse FGF19 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.
