丝聚合蛋白(FLG)是一种丝状相关蛋白,与上皮细胞的角蛋白纤维结合。在表 皮细胞的终端分化过程中,Filaggrin 单体串联成一个 350kDa 的大蛋白前 体,被称为 profilaggrin。在表皮中,这些结构存在于颗粒层细胞的角蛋白 颗粒中。Profilaggrin 在颗粒层和角质层之间的过渡期经历了蛋白质分解过 程,产生了单独的丝状蛋白单体,这可能是由钙依赖性的酶促成的。它的特 点是等电点特别高,这是因为其主要结构中组氨酸的含量相对较高。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人丝聚合蛋白(FLG)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丝聚合蛋白(FLG)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 FLG. 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 FLG 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.
