TARDNA 结合蛋白 43(TDP43)是一种由 TARDBP 基因编码的蛋白质。它有 414 个氨基酸残基,由 4 个结构域组成。一个 N 端结构域,横跨残基 1-76 (NTD),具有明确的折叠,已被证明可以形成二聚体或寡聚体;个高度保 守的折叠 RNA 识别基团,分别横跨残基 106-176(RRM1)和 191-259 (RRM2),需要与目标 RNA 和 DNA 结合。一个非结构化的 C 端结构域, 包括残基 274-414(CTD),它包含一个富含甘氨酸的区域,参与蛋白-蛋 白的相互作用,并包含与家族性肌萎缩侧索硬化症有关的大多数突变。全长 蛋白是一个二聚体。 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TARDNA结合蛋白43(TDP43)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TARDNA结合蛋白43(TDP43)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 TDP43. 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 TDP43 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.
