成纤维细胞生长因子 18,也被称为 FGF-18,是由 FGF-18 基因编码的蛋白 质。该基因编码的蛋白质是成纤维细胞生长因子(FGF)家族的成员。FGF 家族 成员具有广泛的促有丝分裂和细胞存活活性,并参与多种生物学过程,包括 胚胎发育、细胞生长、形态发生、组织修复、肿瘤生长和侵袭。体外研究表 明,这种蛋白质能够在 PC12 细胞中诱导神经突生长。它通过成纤维细胞生 长因子受体 FGFR3 发出信号以促进软骨形成,并已被证明会导致骨关节炎小 鼠模型中的软骨增厚, 它的重组版本(sprifermin)正在临床试验中作为骨关 节炎的潜在治疗方法。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人成纤维细胞生长因子18(FGF-18)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成纤维细胞生长因子18(FGF-18)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 FGF-18. 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 FGF-18 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.
