心肌肌钙蛋白Ⅰ(cTn-Ⅰ)是心脏调节蛋白,控制钙介导的肌动蛋白和肌球蛋白之间的互动。这些调节蛋白的心脏形式是由特定的基因编码的,它为心肌组织特有的一种调节蛋白,可抑制肌球蛋白与肌动蛋白结合,在心肌收缩过程中起重要作用。大量研究表面,在急性心肌梗死早期cTn-Ⅰ水平变化幅度较大,具有较高的敏感性,且cTn-Ⅰ不在任何类型的骨骼肌中表达,具有较高的心肌细胞特异性。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人心肌肌钙蛋白Ⅰ(cTn-Ⅰ)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心肌肌钙蛋白Ⅰ(cTn-Ⅰ)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 cTn-Ⅰ. 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 cTn-Ⅰ 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.
