补体成分 1S（C1S）由C1S基因编码，是补体系统的重要组成部分，来源于人体肝脏合成，具有丝氨酸蛋白酶活性。它参与补体激活的典型途径，当抗原抗体复合物与 C1q 结合后，会激活 C1r 并相继激活 C1s，形成 C1qr2s2 复合物，进而引发补体级联反应，导致炎症发生。C1S 在免疫系统中起着关键作用，不仅是补体系统的重要组分，还参与免疫反应的调控和炎症的调节。其功能障碍与多种疾病相关，如自身免疫性溶血性贫血等。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人补体成分1S(C1S)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补体成分1S(C1S)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 C1S. 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 C1S 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.
