紧密连接蛋白,也被称为 Occludin,是由 Occludin 基因编码的酶。它是一 种氧化 NADH 的酶。它首先在上皮细胞中被鉴定为位于紧密连接处的 65kDa 完整质膜蛋白。与 Claudins 和 zonula occludens-1 (ZO-1) 一起,它被认 为是紧密连接的主要成分。它不仅存在于上皮/内皮细胞中,而且还在没有紧 密连接但代谢非常活跃的细胞中大量表达:周细胞、神经元和星形胶质细胞、 少突胶质细胞、树突细胞、单核细胞/巨噬细胞 淋巴细胞和心肌。它影响细 胞代谢的关键方面,如葡萄糖摄取、ATP 产生和基因表达。它在维持紧密连 接的阻隔特性方面起着关键作用。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠紧密连接蛋白(Occludin)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紧密连接蛋白(Occludin)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 Occludin. 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 Occludin 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.
