甲胎蛋白（AFP，α-胎儿蛋白；有时也称为α-1-胎儿蛋白、α-胎儿球蛋白或α-胎儿蛋白）是一种蛋白质，由AFP基因编码。 AFP基因位于4号染色体的q臂（4q25）。母体AFP血清水平可用于筛查唐氏综合征、神经管缺陷和其他染色体异常 。AFP是胎儿发育过程中由卵黄囊和胎儿肝脏产生的一种主要血浆蛋白。它被认为是血清白蛋白的胎儿类似物。AFP与铜、镍、脂肪酸和胆红素结合，以单体、二聚体和三聚体形式存在。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有大鼠甲胎蛋白(aFP)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大鼠甲胎蛋白(aFP)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 Rat aFP. 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 Rat aFP 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.
