紧密连接蛋白1,也被称为ZO-1或TJP1,是由TJP1基因编码的外周膜蛋白。它属于zonula闭塞蛋白家族(ZO-1,ZO-2和ZO-3),它们是紧密连接相关蛋白,其中ZO-1是第一个被克隆的。1986年,Stevenson和Goodenough使用啮齿动物肝脏中培养的单克隆抗体首次分离出它,以识别全肝匀浆和紧密连接富集膜级分中的225-kD多肽。它具有作为支架蛋白的作用,其交联并锚定紧密连接(TJ)链蛋白,这些紧连接(TJ)链蛋白是脂质双层内的原纤维状结构,与肌动蛋白细胞骨架相连。编码的蛋白质可能参与细胞-细胞连接处的信号转导。已经为该基因鉴定了两个编码不同亚型的转录本变体。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人紧密连接蛋白1(ZO-1)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紧密连接蛋白1(ZO-1)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 ZO-1. 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 ZO-1 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.
