磷酸化外纺锤体极样蛋白1(ESPL1)是一种参与细胞有丝分裂的关键蛋白,属于分离酶(separase)家族。ESPL1通过其蛋白酶活性,在细胞分裂的后期阶段切割黏连蛋白复合体的亚基SCC1(RAD21),从而解除姐妹染色单体间的黏连,促进染色体的正确分离。这一过程对于维持基因组的稳定性和染色体数目正常传递至关重要。ESPL1的活性受到严格的磷酸化调控。在有丝分裂前期,ESPL1被抑制性磷酸化修饰而失活;当细胞进入分裂后期,通过特定激酶的去磷酸化作用,ESPL1被激活并发挥其蛋白酶功能。ESPL1的异常表达或调控失常可能导致染色体分离错误,进而引发染色体数目异常,与肿瘤发生、发育缺陷等疾病密切相关。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人磷酸化外纺锤体极样蛋白1(ESPL1)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磷酸化外纺锤体极样蛋白1(ESPL1)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 ESPL1. 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 ESPL1 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.
