间隙连接α-1蛋白(GJA1),也被称为连接蛋白43(Cx43),由6号染色体上的GJA1基因编码的蛋白质。作为一种连接蛋白,GJA1是间隙连接的一个组成部分,它使细胞间的间隙连接细胞间通讯(GJIC)能够调节细胞死亡、增殖和分化。由于其功能,GJA1与许多生物过程有关,包括肌肉收缩、胚胎发育、炎症和精子生成,以及疾病,包括眼球发育不良(ODDDD)、心脏畸形和癌症。GJA1是一个由382个氨基酸组成的43.0kDa的蛋白质。它含有一个长的C端尾巴,一个N端结构域和多个跨膜结构域。该蛋白四次穿过磷脂双分子层,使其C端和N端暴露在细胞质中。C端尾巴由50个氨基酸组成,包括翻译后修饰位点,以及转录因子、细胞骨架元素和其他蛋白的结合位点。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人间隙连接蛋白43(CX43)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间隙连接蛋白43(CX43)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 CX43. 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 CX43 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.
