表面活性剂蛋白 A 是一种先天免疫系统集合素。它是水溶性的，具有与 SP-D 相似的胶原蛋白结构域。它是先天性免疫系统的一部分，用于在肺泡中对细 菌细胞进行杀灭，使其被肺泡巨噬细胞吞噬。SP-A 也可能在限制肺部表面活 性剂分泌的负反馈中起作用。SP-A 不是肺部表面活性剂发挥作用的必要条 件，但确实赋予生物体以免疫作用。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有小鼠肺表面活性物质相关蛋白A(SP-A)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小鼠肺表面活性物质相关蛋白A(SP-A)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 Mouse SP-A. 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 Mouse SP-A 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.
